Narrated Ibn 'Abbas:

When Allah's Apostle was on his death-bed and in the house there were some people among whom was 'Umar bin Al-Khattab, the Prophet ﷺ said, "Come, let me write for you a statement after which you will not go astray." 'Umar said, "The Prophet is seriously ill and you have the Qur'an;
so the Book of Allah is enough for us." The people present in the house differed and quarrelled. Some said "Go near so that the Prophet may write for you a statement after which you will not go astray," while the others said as Umar said. When they caused a hue and cry before the Prophet, Allah's Apostle ﷺ said, "Go away!" Narrated 'Ubaidullah: Ibn 'Abbas used to say, "It was very unfortunate that Allah's Apostle was prevented from writing that statement for them because of their disagreement and noise."
