وعن علي قال : كان لي من رسول الله صلى الله عليه وآله وسلم مدخلان فكنت إذا أتيته وهو يصلي تنحنح لي .رواه النسائي وابن ماجه.
Narrated Ali (RA): "I had the permission of Allah's Messenger (ﷺ) to see him in his house at two times, and whenever I entered to him while he was praying he would clear his throat as a sign to me." [Reported by an-Nasa'i and Ibn Majah].
