Musnad Ahmad 2967
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn 'Abbas (رضي الله عنه) said: When the Messenger of Allah (ﷺ) was dying, he said: "Come, let me write for you a document after which you will not go astray.” There were some men in the house, among whom was 'Umar bin al-Khattab. 'Umar said: The Messenger of Allah (ﷺ) is overcome with pain, and you have the Qur'an, and the Book of Allah is sufficient for us. The people in the house disagreed, and they argued. Some of them said: Let the Messenger of Allah (ﷺ) write (something) for you, or they said: Bring something and let the Messenger of Allah (ﷺ) write (something) for. Others agreed with what ‘Umar said. When their disagreement and argument became too much and the Messenger of Allah (ﷺ) became overwhelmed, he said: "Get up and leave.” Ibn 'Abbas used to say: What a calamity it was when The Messenger of Allah (ﷺ) was prevented from writing that document for them because of their disagreement and argument.
