عن ابن عمر رضي الله عنهما أن رسول الله صلى الله عليه وآله وسلم قال: « ما حق امرىء مسلم له شيء يريد أن يوصي فيه يبيت ليلتين إلا ووصيته مكتوبة عنده ». متفق عليه.
Narrated Ibn 'Umar (RA): Allah's Messenger (ﷺ) said: "It is not permissible for a Muslim person, who has something he wants to give as a bequest, to have it for two nights without having his will regarding it written and kept ready with him." [Agreed upon].
