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» ."

Rabi’ bin Khuthaym, may Allah have mercy on him, made a bequest:“I call Allah to witness, and Allah is sufficient as a witness, that I accept Allah as my Lord, Islam as my religion, and Muhammad (peace be upon him) as my Prophet. And I desire to be among those who obey me from among the worshippers of Allah, to be among those who give thanks to Allah, and to be among the well-wishers of the community of Muslims.”

Ja'far bin Iyas, may Allah have mercy on him, wrote in his will: "I bear witness that there is no deity except Allah and that Muhammad (peace be upon him) is Allah's servant and Messenger. The Day of Judgment is coming, there is no doubt about it, and Allah will resurrect (people) from the graves. I accept Allah as my Lord, Islam as my religion, and Muhammad (peace be upon him) as my Prophet. Upon this I will live, upon this I will die, and upon this I will be raised. And I advise my family to fear Allah and to hold fast to Islam at the time of death."

Abu Ishaq (may Allah have mercy on him) narrated, he said: "I heard this hadith from Sila bin Zufar (may Allah have mercy on him) seventy years ago, he said: A man came to Abdullah bin Mas'ud (may Allah be pleased with him) on a horse or a piebald horse and said: Do you command me to buy this? He said: What is the matter with it? He said: A man made a bequest to me and this is from his inheritance, and I took it to the market and its price was established for me." Abdullah bin Mas'ud (may Allah be pleased with him) said: "Whoever takes something of a deceased person to the market because he is the executor, he should neither buy it himself nor take a loan from it."
