Malik related to me from al-Ala ibn Abd ar-Rahman from Mabad ibn Kab as-Salami from his brother Abdullah ibn Kab ibn Malik al-Ansari from Abu Umama that the Messenger of Allah, may Allah bless him and grant him peace, said, "Whoever cuts off the right of a muslim man by his oath, Allah forbids him the Garden and obliges the Fire for him." They said, "Even if it is something insignificant, Messenger of Allah?" He said, "Even if it is a tooth-stick, even if it is a tooth- stick," repeating it three times.

The Prophet said, "Whoever takes the property of a Muslim by taking a false oath, will meet Allah Who will be angry with him." Then the Prophet recited the Verse:-- 'Verily those who purchase a small gain at the cost of Allah's Covenant and their oaths, they shall have no portion in the Hereafter, neither will Allah speak to them, nor look at them.' (3.77)

Allah's Apostle said, "It is not permissible for any Muslim who has something to will to stay for two nights without having his last will and testament written and kept ready with him."

The Prophet said, "The most hated persons to Allah are three: (1) A person who deviates from the right conduct, i.e., an evil doer, in the Haram (sanctuaries of Mecca and Medina); (2) a person who seeks that the traditions of the Pre-lslamic Period of Ignorance, should remain in Islam (3) and a person who seeks to shed somebody's blood without any right."

Malik related to me from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "It is the duty of a muslim man who has something to be given as a bequest not to spend two nights without writing a will about it."

Malik said, "The generally agreed-on way of doing things in our community is that when the testator writes something in health or illness as a bequest, and it has freeing slaves or things other than that in it, he can alter it in any way he chooses, until he is on his deathbed. If he prefers to abandon a bequest or change it, he can do so unless he has made a slave mudabbar (to be freed after his death). If he has made him mudabbar, there is no way to change what he has made mudabbar. He is allowed to change his testament because the Messenger of Allah, may Allah bless him and grant him peace, said, "It is the duty of a muslim man who has something to be given as a bequest not to spend two nights without writing a will about it."

Malik explained, "Had the testator not been able to change his will nor what was mentioned in it about freeing slaves, each testator might withhold making bequests from his property, whether in freeing slaves or other than it. A man gives a bequest in his health and in his travelling." (i.e. he does not wait till his death bed ) .

Malik summed up, "The way of doing things in our community about which there is no dispute is that he can change whatever he likes of that except for the mudabbar."
