Sayyiduna Anas bin Malik, may Allah be pleased with him, said: "People used to write at the beginning of their wills: This is the will of so-and-so, son of so-and-so, who bears witness that there is no deity except Allah, He is alone, He has no partner, and Muhammad (peace and blessings be upon him) is His servant and Messenger, and that the Hour will certainly come, there is no doubt about it, and Allah will resurrect those who are in the graves. He would enjoin his family to fear Allah, to reconcile among themselves, to obey Allah and His Messenger (peace and blessings be upon him), and would remind them of the will of Ibrahim and Yaqub, peace be upon them «يَا بَنِيَّ إِنَّ اللَّهَ اصْطَفَىٰ لَكُمُ الدِّينَ فَلَا تَمُوتُنَّ إِلَّا وَأَنْتُمْ مُسْلِمُونَ» ."
