The Statement of Allah aza'wajal: "... After the payment of legacies he may have bequeathed or debts..."
It is mentioned that Shuraih, Umar bin Abdul-Aziz, Tawus, Ata and Ibn Udhaina regarded as valid the acknowledgement of a debt by a sick man. Al-Hasan said, "The most valid charity is what is given on the last day of one's present life and the first day of the life to come (i.e., on the day one dies)."
Ibrahim and Al-Hakam said, "If a sick person absolves an heir from debt, the heir is regarded as absolved." Rafi bin Khadij made a will that his Fazariyya wife should not let anybody share with her the contents of her house.
Al-Hasan said, "If somebody on his deathbed says to his slave, 'I have freed you', the manumission is valid."
Ash-Sha'bi said, "If a dying woman says, 'My husband has paid what he owed me and I have received it,' her confession is valid." Some people say, "The dying person's confession (of debt to some of his heirs) is not valid because such a confession rouses suspicion." But they approve of a confession concerning a trust, goods, and silent partnership, but the Prophet (ﷺ) ﷺ said, "Avoid suspicion, suspicion is the worst of false tales."
It is not legal for one to eat up the Muslims' wealth (unjustly), for the Prophet (ﷺ) ﷺ said, "The sign of a hypocrite is that when he is entrusted with something he proves treacherous." And Allah تعالى said:
"Verily! Allah commands that you should render back the trusts to those to whom they are due..." (V.4:58), without restricting this order to the heirs or some other people.
