Mukhtasar Muslim (Abridged) 981 — Encouragement to make a will

Salim narrates from Sayyiduna Ibn Umar (may Allah be pleased with them) that he heard the Messenger of Allah (peace and blessings be upon him) say: "It is not befitting for a Muslim who has something to bequeath, that he should spend three nights without having his will written with him." Sayyiduna Abdullah bin Umar (may Allah be pleased with them) said: "Since I heard this hadith from the Messenger of Allah (peace and blessings be upon him), not a single night has passed for me without my will being with me."
