BASIC SOURCE OF ISLAM
Islam is a precious gift from Allah to His Creations that guides them from darkness to light. It’s a monotheistic and complete religion based on the Qur'aan and Sunnah of Prophet Muhammad ﷺand as per the understanding of Sahaba Ikram (companions of Prophet Muhammad ﷺ)
Allah has completed His Deen as stated in the Noble Qur’aan: “This day, I have perfected your religion for you, completed My Favor upon you, and have chosen for you Islam as your religion”. Qur’an Surah Maidah 5:3
For a Muslim who doesn’t want to go astray, it is necessary to refer to the Qur'aan and Sunnah of the Prophet Muhammad (peace be upon him) for all the matters. Allah says in the Qur’an: “O you who believe! Obey Allah and the Messenger and those of you (Muslims) who are in authority. (And) if you differ in anything amongst yourselves, refer it to Allah and His Messenger (peace be upon him), if you believe in Allah and in the Last Day. That is better and more suitable for final determination.” Qur’an Surah Nisa 4:59
For true guidance we have to believe as the Sahaba(companions of Prophet Muhammad ﷺ) believed. Allah says in the Qur’an:So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allah will be sufficient for you against them. And He is the Hearing, the Knowing. Qur’an Surah Nisa 2:137. Further Allah says: And whoever opposes the Messenger after guidance has become clear to him and follows other than the way of the believers - We will give him what he has taken and drive him into Hell, and evil it is as a destination. Qur’an Surah Nisa 4:115
Messenger of Allah(S) Said: "I have left two matters with you. As long as you hold to them, you will not go the wrong way. They are the Book of Allah and the Sunna of His Prophet. "
رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " تَرَكْتُ فِيكُمْ أَمْرَيْنِ لَنْ تَضِلُّوا مَا تَمَسَّكْتُمْ بِهِمَا كِتَابَ اللَّهِ وَسُنَّةَ نَبِيِّهِ
Muwatta Malik, the book of Decree Book 46, Hadith 3 (Arabic: Book 46, Hadith 1626) and and Baihaqi 20833
Famous Islamic scholars urge adherence to Islamic sources rather than making divisions in Islam and following them blindly, and none of them have asked to establish a sect in their names.
Shaykh Ibn Taymiyyah(may Allah have mercy on him), said:
"And the four Imaams, may Allaah be pleased with them, all forbade the people from blindly following them in all that they may say; and this was an obligation upon them [to do]."
Shaykh Ibn Taymiyyah(may Allah have mercy on him) said,
“Indeed the people of truth and the Sunnah do not follow anyone [unconditionally] except the Messenger of Allah (peace be upon him), the one who does not speak from his desires - it is only revelation revealed to him.” Shaykh Ibn Taymiyyah, Majmoo'ah al-Fataawaa, vol 3, page 216, Daar Ibn Hazm Print, Trans: Aboo 'Abdis-Salaam
Imam Abu Haneefah(may Allah have mercy on him) said:
“Adhere to the athar (narration) and the tareeqah (way) of the pious predecessors and beware of newly invented matters for all of it is innovation” (As-Suyootee in Sawn al Mantaq wal-Kalaam p.32)
He also said in a famous statement, “When a Hadith is found to be saheeh, then that is my madhab (religion), Ibn 'Aabideen in al-Haashiyah 1/63, and in his essay Rasm al-Mufti (1/4 from the Compilation of the Essays of Ibn 'Aabideen), Shaikh Saalih al-Fulaani in Eeqaaz al-Himam (p. 62).” And “It is haram (prohibited) for someone who does not know my evidence to give fatwaa (verdicts) on the basis of my words.” Another narration adds, “... for we are mortals; we say something one day, and take it back the next day.” Ibn al-Qayyim in I'laam al-Mooqi'een (2/309), Ibn 'Aabideen in his Footnoes on Al-Bahr ar-Raa'iq (6/293) and in Rasm al-Mufti (pp. 29, 32) & Sha'raani in Al-Meezaan (1/55) with the second narration. Similar narrations exist on the authority of Abu Haneefah's companions Zafar, Abu Yoosuf and 'Aafiyah ibn Yazeed; cf. Eeqaaz (p. 52). Ibn al-Qayyim firmly certified its authenticity on the authority of Abu Yoosuf in I'laam al-Mooqi'een (2/344)
And “When I say something contradicting the Book of Allah the Exalted or what is narrated from the Messenger, then ignore my saying.” Al-Fulaani in Eeqaaz al-Himam (p. 50), tracing it to Imaam Muhammad and then saying, "This does not apply to the mujtahid, for he is not bound to their views anyway, but it applies to the muqallid."
Imam Maalik ibn Anas (May Allah have mercy on him) said:
“Truly I am only a mortal. I make mistakes (sometimes) and I am correct (sometimes). Therefore, look into my opinions; all that agrees with the Book and the Sunnah, accept it; and all that does not agree with the Book and the Sunnah, ignore it.” (Ibn ‘Abdul Barr in Jaami’ Bayaan al-’Ilm,(2/32), Ibn Hazm, quoting from the former in Usool al-Ahkaam (6/149), & similarly Al-Fulaani (p. 72))
"Indeed I am a human, I can make mistakes, and I can be correct, so look into my opinion, everything that is in agreement with the Book and the Sunnah, then take it, and everything that does not agree with the Book and the Sunnah then leave it."
Imam Shaafi’i(May Allah have mercy on him) said:
“The Sunnah of the Messenger of Allah (peace be upon him) reach, as well as escape from, every one of us. So whenever I voice my opinion, or formulate a principle, where something contrary to my view exists on the authority of the Messenger of Allah (peace be upon him), then the correct view is what the Messenger of Allah (peace be upon him) has said, and it is my view.” Related by Haakim, with a continuous sanad up to Shaafi'i, as in Taareekh Dimashq of Ibn 'Asaakir (15/1/3), I'laam al- Mooqi'een (2/363, 364) & Eeqaaz (p. 100). "
The Muslims are unanimously agreed that if a sunnah of the Messenger of Allaah (sal-Allaahu 'alayhe wa sallam) is made clear to someone, it is not permitted (not Halaal) for him to leave it for the saying of anyone else
"In every issue where the people of narration find a report from the Messenger of Allaah (sal-Allaahu 'alayhe wa sallam) to be saheeh which is contrary to what I have said, then I take my saying back, whether during my life or after my death.
For everything I say, if there is something authentic from the Prophet (sal-Allaahu 'alayhe wa sallam) contrary to my saying, then the hadeeth of the Prophet (sal-Allaahu 'alayhe wa sallam) comes first, so do not follow my opinion.
Ahmad ibn Hanbal(May Allah have mercy on him) said:
“Do not follow my opinion; neither follow the opinion of Maalik, nor Shaafi’i, nor Awzaa’i, nor Thawri, but take from where they took.” Ibn 'Abdul Barr in Jaami' Bayaan al-'Ilm (2/149), Fulaani (p. 113) & Ibn al-Qayyim in I'laam (2/302)
“Do not copy your Deen (religion) from anyone of these, but whatever comes from the Prophet (peace be upon him) and his companions, take it; next are their successors, where a man has a choice.”(i.e. to accept it or reject it). Abu Daawood in Masaa'il of Imaam Ahmad (pp. 276-7)“Whoever rejects a statement of the Messenger of Allah (peace be upon him) is on the brink of destruction.” (Ibn al-Jawzi p. 182)
Therefore, the path that can lead a Muslim to paradise is the same as the one that was taken by Muhammadﷺand his companions. Whoever follows this path shall be successful and whoever deviates from it shall be doomed. “Indeed in the Messenger of Allah you have an excellent example to follow” Qur’an Surah Al Ahzaab 33:21
