This book deals with the importance of having an Islamic will. Author Hisham Ibn Fahmi Ibn Moussa AlAref, through textual proofs of the Holy Quran and the Sunnah of the Prophet Muhammad, peace be upon him, explained what a will is and how important it is in Islam. Islam highly encourages, if not obligates, writing a will as soon as possible, since one does not know when Allah will take the Muslim's soul back to Him. Many manmade laws also recognize such importance, while its absence brings endless problems. It can include both financial and religious matters and can be a document for reference and application without disputes.
