Ibn Awn said: The will of Ibn Sirin (may Allah have mercy on him) was: Muhammad bin Abi Amrah enjoined upon his children and the children of his family that they "fear Allah, set things right among themselves, and obey Allah and His Messenger (peace and blessings be upon him), if they are believers" [Surah al-Anfal: 1]; and he enjoined upon them what Ibrahim and Ya'qub (peace be upon them) enjoined upon their sons: "O my sons, Allah has chosen the religion for you, so do not die except in a state of Islam" [Surah al-Baqarah: 132]; and he enjoined upon them not to give up being brothers of the Ansar and their mawali (clients), for chastity and truthfulness are more God-fearing and more honourable than fornication and lying; and he gave them instructions concerning what he left behind, in case something should befall me before I change my will.
