WORSHIP IN RAMAZAAN
Worship is submission to Allah with utmost humility and love of Him.
Shaykhul-Islaam Ibn Taymiyyah(d.728H) – Rahimahullaah – said:
“Worship (al-’Ibaadah) is obedience to Allaah by following that which He ordered upon the tongues of His Messengers.” He also said, “Worship (al-’Ibaadah) is a comprehensive term covering everything that Allaah loves and is pleased with – whether saying, or actions, outward and inward.” Majmoo’ul-Fataawaa (10/149) of Ibn Taymiyyah 
Below are the lists of worships possible in the month of Ramazaan:
“O you who believe! Observing al‐siyaam (the fast) is prescribed for you as it was prescribed for those before you, that you may become al‐muttaqoon (the pious).” [Surah al‐Baqarah 2:183]
Allaah encourages His slaves to fast : “… And that you fast, is better for you, if only you know.” [Surah al‐Baqarah 2:184]
Allah's Messengerﷺsaid, "Whoever observes fasts during the month of Ramadan out of sincere faith, and hoping to attain Allah's rewards, then all his past sins will be forgiven." Sahih Al-Bukhari Vol 1:38 and Vol 3:125 
Tarawih,is a voluntary prayer by which a true believer intends to seek the pleasure of Allaah and draw near to Him. Allaah's Messengerﷺ has encouraged offering prayer at night regularly. This prayer is known as the 'night prayer' (Qiyamul-Layl) or (Tahajjud). During Ramazaan this prayer is also called as Tarawih. It is allowed to offer the Tarawih, at any time starting from the conclusion of' Isha (Night) prayer until the commencement of the Fajr (Dawn) prayer.
Narrated Abu Salma bin `Abdur Rahman: I asked `Aisha, "How is the prayer of Allah's Messenger (ﷺ) during the month of Ramadan." She said, "Allah's Messenger (ﷺ) never exceeded eleven rak`at in Ramadan or in other months; Sahih Bhukari 1147 and 2013 NE (Vol 2, Book 21 Hadith 248, Vol 3:230 and Vol. 8, Book 75, Hadith 322), Sahih Muslim 736 a (Book 4, Hadith 1602), Sunan Abi Dawud 1335 , Jami` at-Tirmidhi 440, Sunan Nasai Vol 2:1697
The Prophetﷺsaid: "Whoever performed the night prayer (Qiyamul Layl) in Ramazaan with sincere faith and hoping for a reward from Allaah, then all his past sins will be forgiven." Sahih al Bukhari 2008 (Vol 3:226 and Vol 1:37) 
One of the special deeds of Ramazaan is Iti’kaf. Performing Iti’kaf means to confine oneself in seclusion in a masjid for the purpose of worshipping Allaah alone, leaving every worldly and personal affair.
Allaah’s Messengerﷺperformed Iti’kaf in the last ten days of the month of Ramazaan. Sahih Al-Bukhari 2025 (Vol. 3, Book 33, Hadith 242)
Allaah says (interpretation of the meaning): “And do not have sexual relations with them (your wives) while you are in Iti’kaf (i.e. confining oneself in a mosque for prayers and invocations leaving the worldly activities) in the mosques” Qur’an Surah Baqarah 2:187
It is not valid for men or women to observe Iti’kaf anywhere but in the mosque; it is not valid in the mosque of a woman’s house or the mosque of a man’s house, which is a space that is set aside for prayer. Al-Nawawi said in al-Majmoo’ (6/505) 
The Night of Decree (Laylatul-Qadr) is more virtuous and meritorious than a thousand months. It is the night of Ramazaan in which the Qur'an was brought from lohe Mahfuz to Baitul Izza. Allaah says in the Glorious Qur'an: "Verily, We have sent it (this Qur'an) down in the Night of Decree (Al-Qadr). And what will make you know what the Night of Decree is? The Night of Decree is better than a thousand months." Qur’an Surah Qadr 97:1-3
The only thing that is clear concerning its time is that it occurs during the last ten nights of Ramazaan(odd nights of last 10 days i.e., 21,23,25,27 and 29 of Ramazaan). Sahih Al-Bukhari 2020 (Vol. 3, Book 32, Hadith 237)
Dua to be read on odd nights of last 10 days i.e., 21, 23, 25, 27 and 29 of Ramazaan
اَللَّهُمَّ اِنَّكَ عَفُوٌّ ، تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي
'Allaahumma innaka 'afuwwun tuhibbul-'afwa, fa'fu 'anni. Meaning: O Allaah, You are Forgiving and love forgiveness, so forgive me. Ibn Majah Vol. 5, Book 34, Hadith 3850 and Jami at Tirmidhi 3513
ProphetﷺSaid: Whoever stood for the prayers in the night of Qadr out of sincere Faith and hoping for a reward from Allaah, then all his previous sins will be forgiven ." Sahih Al-Bukhari 2014 (Vol. 3, Book 32, Hadith 231 and Vol 1:35) 
Zakat ul-fitr or Sadqat ul-fitrmeans "the purifying charity of breaking the fast". It is a prescribed amount of food given by the Muslims during the last few days of Ramazaan if collected by some authority or on the morning of Eid prior to the Eid prayer.
The best time to pay Zakatul-Fitr is the time from dawn on 'Eid Day (the first day of the Month of Shawwal) until just before the 'Eid prayer, Sahih Al-Bukhari 1503. However, those who give it before the morning of the 'Eid (i.e. a day or two before the 'Eid) have properly fulfilled the obligation. Those who give it away after the 'Eid prayer, it is considered as a voluntary charity (Sadaqah) only. In other words it is not counted as Zakatul-Fitr.
The Prophet's Companion Abu Sa'eed Al-Khudri said: "In the lifetime of Allaah's Messengerﷺwe used to give Zakatul-Fitr on behalf of the young and the old, the free man and the slave, as one Sa’ of food, or one Sa' of cottage cheese, or one Sa’ of barley, or one Sa’ of dates or one Sa’ of raisins." Sahih Al-Bukhari 1510 (Vol. 2, Book 25, Hadith 586) 
Zikr Of Allaah during Ramazaan or Any Other Month: The Messenger of Allaahﷺsaid: “The comparison of the one who remembers Allaah and the one who doesn’t is like that of the living and the dead.” Sahih Al-Bukhari 6407 NE (Vol. 8: 416)
And more Such as saying Subhaan-Allaah, La ilaaha illa-Allaah, al-Hamdu Lillaah, etc. you can repeat the words “Subhaan-Allaah wa’l-hamdu Lillaah, wa laa ilaaha ill-Allaah, wa Allaahu akbar (Glory be to Allaah, praise be to Allaah, there is no god but Allaah and Allaah is Most Great)” and “Subhaan Allaahil-‘Azeem, SubhaanAllaahi wa bi hamdihi, (Glory and praise be to Allaah, glory be to Allaah the Almighty)” etc. 
Narrated Ibn 'Abbas(R): Allah's Messenger (ﷺ) was the most generous of all the people, and he used to reach the peak in generosity in the month of Ramadan when Gabriel met him. Gabriel used to meet him every night of Ramadan to teach him the Qur'an. Sahih al-Bukhari 6
Ramazaan is the month of Quran, Imam Malik used to quit reading the Hadith and sitting with the scholars and turned to reciting the Quran from the Book.”
Allah said: The month of Ramazaan [is that] in which was revealed the Qur'an, a guidance for the people and clear proofs of guidance and criterion. Quran Surah Baqrah 2:185
Narrated Muhammad bin Ka'b Al-Qurazi:"I heard 'Abdullah bin Mas'ud saying: 'The Messenger of Allah (ﷺ) said: "[Whoever recites a letter] from Allah's Book, then he receives the reward from it, and the reward of ten the like of it. I do not say that Alif Lam Mim is a letter, but Alif is a letter, Lam is a letter and Mim is a letter." Jami at-Tirmidhi, Vol. 5, Book 42, Hadith 2910  See more
Allah said in the Qur'an: "And those who hoard gold and silver and spend it not in the way of Allaah - give them tidings of a painful punishment."Qur’an Surah Tawbah 9:34
Zakath comes under compulsory act for those who fits on Nisab (required amount). The payment of Zakath is obligatory, as it is one of the five pillars of Islam,Sahih Al Bukhari Vol 1:8.
Every Muslim male or female who at the end of the Hijri year is in possession of the equivalent of 85 grams of gold(71/2 Tolas) or more in cash or 595 grams of silver(521/2 Tolas ), must pay his or her Zakath at the minimum rate of 2.5%. See more
Charity means Something given to help the needy by giving money, food, etc. There are two forms of charity in Islam - obligatory and voluntary, called zakath and sadaqa respectively.Allah (Glory be to Him) says: “O you who believe! Spend of that with which We have provided for you, before a Day comes when there will be no bargaining, nor friendship, nor intercession. And it is the disbelievers who are the Zaalimoon (wrongdoers)” Qur’an.Surah Baqarah 2:254
It was narrated from Abu Hurayrah (R) that the Prophet Muhammad (May Allah honour Him and Grant Him peace) said: “There is no day on which the people get up but two angels come down and one of them says, ‘O Allah, give in compensation to the one who spends (in charity),’ and the other says, ‘O Allah, destroy the one who withholds.’” Sahih Al Bukhaari, 1374 and Sahih Al Muslim, 1010
"Charity extinguishes sin as water extinguishes fire." Tirmidhi 2541 
Umrah is an Islamic rite and consists of pilgrimage to the Ka‘bah. A set of religious and devotional rites performed in Makkah at any time of the year in a state of dress and condition known as Ihram with the intention of performing certain religious rites there according to the method prescribed by the Prophet Muhammad (May Allah honour Him and grant Him peace). It has also been referred to in English as the minor pilgrimage andmajor pilgrimage being the Hajj.
The virtue of the Umrah performed during Ramazaan is equivalent to Hajj. Allah's Messenger (ﷺ) said: So when the month of Ramazaan come, perform Umra, for 'Umra in this (month) is equal to Hajj with me (in reward). Sahih al-Bukhari 1863, Sahih Muslim 1255 and Sunan an-Nasa'i 2110  see more
And turn to Allah in repentance, all of you, O believers, that you might succeed. Quran Surah 24:31
The Prophet Muhammad (ﷺ) said: “By Allah (Glory be to Him), I seek the forgiveness of Allah (Glory be to Him) and I turn to Him in repentance more than seventy times each day.” Sahih Al Bukhari, vol 8:319
In other hadees, narrated from al-Agharr ibn Yasaar (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “O people, repent to Allaah for I repent to Him one hundred times each day.” Sahih Muslim 2702
Narrated on the authority of 'Abdullah b. Umar that the Messenger of Allah observed: O womenfolk, you should give charity and ask much forgiveness for I saw you in bulk amongst the dwellers of Hell. A wise lady among them said: Why is it, Messenger of Allah, that our folk is in bulk in Hell? Upon this the Prophet observed: You curse too much and are ungrateful to your spouses. Sahih Muslim 79 
It was narrated from some of the pious predecessors that they used to pray to Allaah for six months that they would live until Ramadaan, then they would pray for five months afterwards that He would accept it from them.
The Muslim should ask his Lord to let him live until Ramadaan with a strong religious commitment and good physical health, and he should ask Him to help him obey Him during the month, and ask Him to accept his good deeds from Him.
Do you know that you have as many as 60 invocations (Duas) answered to in Ramazaan? Prophet said: “Every day and night, a Muslim has an invocation which receives answer.” Sahih at-Targeeb 1002 [Al-Albani authenticated it by the virtue of another hadith]
