Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 92. Holding Fast to the Qur'an and Sunnah
Narrated By Ibn 'Abbas : When the time of the death of the Prophet approached while there were some men in the house, and among them was 'Umar bin Al-Khatttab, the Prophet said, "Come near let me write for you a writing after which you will never go astray." 'Umar said, "The Prophet is seriously ill, and you have the Quran, so Allah's Book is sufficient for us." The people in the house differed and disputed. Some of them said, "Come near so that Allah's Apostle may write for you a writing after which you will not go astray," while some of them said what 'Umar said. When they made much noise and differed greatly before the Prophet, he said to them, "Go away and leave me." Ibn 'Abbas used to say, "It was a great disaster that their difference and noise prevented Allah's Apostle from writing that writing for them.
