The Book of Bequests (Kitab Al-Wasiyya)
Muslim :: Book 13 : Hadith 4016
Ibn Abbas reported: When Allah's Messenger (may peace be upon him) was about to leave this world, there were persons (around him) in his house, 'Umar b. al-Kbattab being one of them. Allah's Apostle (may peace be upon him) said: Come, I may write for you a document; you would not go astray after that. Thereupon Umar said: Verily Allah's Messenger (may peace be upon him) is deeply afflicted with pain. You have the Qur'an with you. The Book of Allah is sufficient for us. Those who were present in the house differed. Some of them said: Bring him (the writing material) so that Allah's Messenger (may peace be upon him) may write a document for you and you would never go astray after him And some among them said what 'Umar had (already) said. When they indulged in nonsense and began to dispute in the presence of Allah's Messenger (may peace be upon him), he said: Get up (and go away) 'Ubaidullah said: Ibn Abbas used to say: There was a heavy loss, indeed a heavy loss, that, due to their dispute and noise. Allah's Messenger (may peace be upon him) could not write (or dictate) the document for them.
