Bequest In Islam
It is explicitly mentioned in the Quran that the law comes into effect after the bequest. The allowance of bequest is general, there is no restriction mentioned with it. With every directive of inheritance, it is mentioned that it is after the debt is paid and the bequest is fulfilled. If the whole estate goes into the payment of debts, even then the law of inheritance will not work. The same goes for the bequest, one is allowed to make a bequest for all of his estate. The only restriction left is the legal one. One is not allowed to change the legal share of his heir. Apart from that, one can give his heir whatever he likes from his property. The law of inheritance came to settle the dispute of inheritance. If the person already settled it through his bequest, there is no dispute, but when a person leaves to his heirs to distribute his estate, then comes the law to save the Muslims from the dispute.
