A will is an instruction by a person for certain tasks to be performed for him after his death. In a will, a person may state that after his death something from his property is to be owned by someone, or that something from his property is to be transferred to someone or be spent on charitable and good causes. In a will, a person may also appoint someone to be the custodian and guardian of his children and dependants. A person who gives effect to a will is called an ‘executor’ (waṣī).
