The sermon of the Messenger of Allah (peace and blessings be upon him) during the Farewell Hajj

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) addressed the people during the Farewell Hajj and said: "Satan has despaired of ever being worshipped (again) in this land of yours, but he is content to be obeyed in those of your deeds which you consider trivial and insignificant; so beware (of Satan), O people! I am leaving among you something which, if you hold fast to it, you will never go astray: the Book of Allah and the Sunnah of His Prophet (peace and blessings be upon him). Indeed every Muslim is the brother of another Muslim; the Muslims are all brothers, and it is not lawful for anyone to take anything of his brother's wealth except what he gives willingly. Do not wrong one another, and do not become disbelievers after me, striking one another's necks."
Imam Bukhari used the hadiths of Ikrimah as evidence and Imam Muslim used Abu Uways Abdullah bin Uways as evidence, and all its other narrators are agreed upon. There is agreement on recording in the "Sahih" the narration of this sermon of the Prophet (peace and blessings be upon him) containing these words: "O people! I am leaving among you that after which you will never go astray if you hold fast to it: the Book of Allah; and you will be asked about me, so what will you say?" The mention of holding fast to the Sunnah in this sermon is gharib (singular), and it is needed.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I am leaving among you two things after which you will never go astray: the Book of Allah and my Sunnah; and these two will never separate until they come to me at the Pond (al-Kawthar)."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that in the blessed time of the Prophet (peace and blessings be upon him) there were two brothers. One of them would stay in attendance on the Prophet (peace and blessings be upon him) (to acquire knowledge), and the other worked for a living. The one who worked complained about his brother to the Prophet (peace and blessings be upon him) (that he did not lend a hand in the work). He (peace and blessings be upon him) said: "Perhaps you are being provided for because of him (by the blessing of your brother)."
This hadith is sahih (authentic) on the condition of Imam Muslim, and all its narrators are firm and trustworthy, but the two Shaykhs did not record it.
