ETIQUETTES OF BATHROOM OR TOILET OR WASHROOM
The Religion of Islam has introduced various manners which Muslims are encouraged to abide by in order to form a complete Islamic personality. Deen E Islam is a complete way of life, guides Muslims in every department of life including bathroom etiquettes.
Among the signs of the greatness of the blessed Islamic sharee’ah is the fact that there is no good thing, major or minor, that it has not commanded us to do or pointed the way to it, and there is no bad thing, major or minor, that it has not warned us against or forbidden. It is perfect and complete in all aspects, a fact which has often greatly astonished non-Muslims and earned their admiration. (At the time of the Prophet ﷺ), one of the mushrikeen (polytheists) said to (the Prophet’s Companion) Salmaan al-Farsi (may Allaah be pleased with him): “Your Prophet has taught you everything, even how to defecate!” Salmaan said: “Yes, he forbade us to face the qiblah when urinating or defecating, performing Istinja (washing the private parts with water after urinating or passing stool) with the right hand, using less than three stones for Istinja, and using dung or bones for Istinja…” Sunan at-Tirmidhi,16; he said it is a saheeh hasan hadeeth; also reported in Sunan Ibn Majah Vol.1: 316 .
Islamic sharee’ah includes a number of rules and manners to be followed when answering the call of nature, including the following:
When one enters the toilet, they should supplicate. Anas(R) said that the Prophet ﷺupon relieving himself would say: “Bismillah Allahumma inni a‘oozu bika min al-khubsi wal-khabaais.” (“I begin with the Name of Allah, O Allah, indeed I seek refuge in you from the male and female Jinn.”) Sunan Abi Dawud , Book 1, Hadith 4, 6
A'ishah (R)said: “When the Messenger of Allah ﷺwould leave the place where he relieved himself, he would say: ‘Ghufraanak’ meaning ‘I seek your forgiveness.’Sunan Abi Dawud , Book 1, Hadith 30 and Sunan Tirmidhi Book 1, Hadith 7
One should conceal himself when he answers the call of nature. Jabir (R) said: “Whenever the Prophet wanted to relieve himself he would retreat to a place where no one could see him.” Abu Dawood
Not to face the qiblah (direction of prayer, i.e. the Ka’bah which was built in Makkah by Ibrahim, upon whom be peace, as commanded by Allaah) when urinating or defecating. This is out of respect for the Qiblah and for the symbols and rituals of Allaah. The Messenger of Allaah ﷺsaid: “When any one of you sits down to answer the call of nature, he should not face the qiblah or turn his back towards it.” Sahih Muslim, 389
One should not face the Qiblah (direction of Mecca) nor give it his back while relieving himself. Abu Hurairah (t) said: “Indeed I am only like a father is to his son. You should not face the Qiblahnor give it your backs (when one of you goes to relieve himself) nor should they wipe themselves with less than three rocks, while not using a piece of dung or a bone” ” Sahih Muslim 262a (book 2 , hadith 504).
He should not touch his penis with his right hand when urinating, because the Prophet ﷺsaid: “When any one of you urinates, he should not hold his penis in his right hand or clean it with his right hand; and (when drinking), he should not breathe into the vessel.” Sahih Al Bukhari, 154, and Sahih al Bukhari Hadith 1648
He should not remove najaasah (impurity) with his right hand; the left hand should be used for this purpose, because of the hadeeth quoted above, and because the Prophet ﷺsaid: “When any one of you wipes himself, he should not use his right hand.” Sahih al-Bukhari, 5199
The Prophet’s wife Hafsah (may Allaah be pleased with her) reported that the Prophet ﷺused to use his right hand for eating, drinking, making wudoo’, getting dressed, and giving and taking things, and he used to use his left hand for other things. Classed as Sahih by sheikh Albani in Sunan Abi Dawud 33, by Imaam Ahmad; see also Saheeh al-Jaami’, 4912. Abu Hurayrah reported that the Messenger of Allaah ﷺsaid: “When any one of you cleans himself, he should not use his right hand, he should use his left hand.” Sunan Ibn Maajah, 308 and Saheeh al-Jaami’, 322
The Sunnah is to answer the call of nature sitting, making oneself close to the ground, because this is more concealing, and makes it less likely that spray from one's urine will come back on one’s body or clothes, making them dirty. If a person can be sure of avoiding this, then it is permissible to urinate standing up. A person should be concealed from the sight of others when answering the call of nature. The Messenger of Allaah ﷺused to prefer to go behind a rise in the ground or a garden of date palms. Sahih Muslim, 517
If a person is out in an open space and cannot find anything to conceal him when he needs to answer the call of nature, he should move far away from the other people around him, because al-Mugheerah ibn Shu’bah said: “I was with the Prophet ﷺon a journey, when he felt the need to answer the call of nature, so he went far away.” Sunan at-Tirmidhi, 20; he said it is a saheeh hasan hadeeth). ‘Abd-Allaah ibn Abi Quraad said: “I went out with the Messenger of Allaah ﷺto an open space, and when he needed to answer the call of nature, he moved away.” Sunan Nisaa’i, 16; Saheeh al-Jaami’, 4651
A person should not uncover his ‘awrah (private parts) until after he has squatted close to the ground, because this is more concealing, as Anas (may Allaah be pleased with him) reported: “When the Prophet ﷺwanted to answer the call of nature, he would not lift his garment until he had squatted close to the ground.” Reported by al-Tirmidhi, 14; see also Saheeh al-Jaami’, 4652
If a person is in a (modern) toilet, he should not lift his garment until he has closed the door and is out of sight of other people. With regard to this point and the one before, it is worth noting that the habit of many people in the West and elsewhere, of urinating in a standing position in front of other people in public toilets (using urinals) is something which goes against good manners, modesty and decency, and is repulsive to anyone who possesses sound common sense and wisdom. How can anybody uncover in front of other people the ‘awrah (private parts) which Allaah has placed between his legs to conceal it and commanded him to cover it? The idea that it should be covered is well established among all wise and decent people of all races. It is wrong in principle to build restrooms of this shameful type, where the users can see one another, thus making them worse than some kinds of animals whose habit is to conceal themselves from one another when urinating or defecating.
It is also good manners according to Sharee’ah to recite certain adhkaar (supplications) when entering or leaving the toilet, which are quite appropriate to the situation and place. Our Prophet ﷺtaught us that when entering the toilet, we should say: “Allaahumma innee a’oozu bika min al-khubsi wa’l-khabaa’is (O Allah, I seek refuge with You from male and female devils).” When leaving the toilet, he should say: “Ghufraanak (I seek Your forgiveness).”
He should be careful to remove all impurity after answering the call of nature, because the Prophet ﷺwarned against being careless in cleaning oneself after urinating: “Most of the punishment of the grave will be because of urine.” Sunan Ibn Maajah, 342; Saheeh al-Jaami’, 1202. Ibn ‘Abbaas (may Allaah be pleased with them both) reported that the Messenger of Allaah ﷺpassed by two graves, and said: “They are being punished, but they are not being punished for any major sin. One of them used not to protect himself (i.e. keep himself clean from) his urine, and the other used to walk about spreading malicious gossip.” Sahih al Bukhari, 5592, Sunan Abi Dawud 20
Any impurity should be washed or wiped three times or an odd number of times greater than three, according to whatever is needed to cleanse it, because ‘Aa’ishah (may Allaah be pleased with her) reported that the Prophet ﷺused to wash his posterior three times. Ibn ‘Umar said: “We did this too and found it to be healing and cleansing.” Sunan Ibn Maajah, 350; Saheeh al-Jaami’, 4993. Abu Hurayrah (may Allaah be pleased with him) reported that the Prophet ﷺsaid: “When anyone of you cleans himself (with stones or similar material) let him use an odd number.” Imaam Ahmad; classed as hasan in Saheeh al-Jaami’, 375
He should not use bones or dung to clean himself or wipe away the impurity, rather, he should use tissue, stones, and the like. Abu Hurayrah (may Allaah be pleased with him) reported that he used to carry a vessel for the Prophet ﷺto do wudoo’ and clean himself after answering the call of nature. Whilst he was following him, he (the Prophet) asked, “Who is that?” He said: “I am Abu Hurayrah.” He said: “Get me some stones I can use to clean myself, but do not bring me any bones or dung.” So I brought him some stones, carrying them in the hem of my garment, and placed them by his side, then I went away. When he had finished, I came back and asked him, “What is wrong with bones and dung?” He said: “They are the food of the jinn.” Sahih al Bukhaari, 3571
A person should not urinate into stagnant water, because Jaabir (may Allaah be pleased with him) reported that the Messenger of Allaah ﷺforbade anyone to urinate into stagnant water,Sahih Muslim, 423, and because this makes the water impure and harms those who use it.
A person should not urinate by the roadside or in places where people seek shade, because this is offensive to them. Abu Hurayrah(R) reported that the Prophet ﷺsaid: “Fear the two things that bring curses.” They asked, “What are the two things which provoke curses, O Messenger of Allaah?” He said: “When a person relieves himself in the road where people walk or in the place where they seek shade.”Sahih Muslim 269,Abu Dawud, 25; Saheeh al-Jaami’, 110
One should not greet a person who is answering the call of nature, or return a greeting whilst one is answering the call of nature, out of respect to Allaah by not mentioning His name in a dirty place. [Translator’s note: the Islamic greeting is “al-salaam ‘alaykum (peace be upon you)”; one of the names of Allaah is al-Salaam (the Peace)]. Jaabir ibn ‘Abd-Allaah reported that a man passed by the Prophet ﷺwhilst he was urinating, and greeted him. The Messenger of Allaah ﷺsaid to him: “If you see me in this state, do not greet me, because if you do, I will not respond.” Sunan Ibn Maajah, 346; Saheeh al-Jaami’, 575 The majority of scholars say that it is makrooh (disliked) to speak in the restroom unnecessarily.
A’isha(R) relates that the Prophet (peace be upon him) used to like to start with the right side when putting on his sandals, combing his hair, engaging in his ritual purifications, and in all of his activities. This is an authentic hadîth related in Sahîh al-Bukhârî 168 and Sahîh Muslim 268b (Book 2, hadith 515) and among other books.
Starting with the right side has two meanings. When there are activities that involve both sides of the body, it means to start with the right side of the body. This is the case when it comes to such activities as washing the hands and putting on shoes. When the activity relates to coming in contact with something, it means to use the right hand instead of the left, as is the case with giving and taking.
This is merely a customary practice. There is no authentic evidence from the Sunnah to support it.
After relating this hadîth, al-Bayhaqî himself says: “This hadîth is one of those to be rejected from Muhammad b. Yûnus al-Kudaymî.”
The second hadîth:
Dov Sikirov discovered it took ‘squatters’ an average of 51 seconds for a bowel movement while ‘sitters’ took an average of 130 seconds. 
The effective removal of excrement from the colon is vital, failure to do so can cause constipation which increases the risk of colon cancer.
In the squat position the large intestine aligns correctly. The thighs supporting the abdomen prevent hernias and massage the intestine into action. The muscular contractions that push food along the digestive tract are hindered by the sitting position, yet assisted by squatting. The squat position eliminates the need for excessive straining alleviating hemorrhoids.
During birth the squatting position gives a greater increase of pressure in the pelvic cavity with minimal muscular effort. The birth canal will open 20—30% more in a squat than in any other position. Squatting will prevent hemorrhoids which often plague pregnant women. Squatting each day on the Lillipad will help prepare the body for this excellent birthing position.
Squatting is a difficult position to adopt straight away, be patient and give yourself a couple of weeks to get used to squatting. The muscles we use to defecate are exercised by getting down into, and up out of, the squat position. Not only will your balance improve, you will also give your spine a beneficial stretch. 
These are some of the rules and manners prescribed by the sharee’ah of Islam in this matter which is repeated many times a day by every person. If the sharee’ah has paid such minute attention to the details of such a mundane matter, what do you think it has to say about more important issues? Do you know of any other religion or system in the world that has brought laws like this? This is enough, by Allaah, to prove its perfection and beauty, and the necessity of following it.
