Riyad as-Salihin, Book 7, Hadith 905 (In-Book) ⓘ

Abu 'Abdullah bin Abul-'as (May Allah be pleased with him) reported: I complained to the Messenger of Allah about a pain I had in my body. The Messenger of Allah said, "Place your hand where you feel pain and say: 'Bismillah (With the Name of Allah)' three times; and then repeat seven times: 'A'udhu bi'izzatillahi wa qudratihi min sharri ma ajidu wa 'uhadhiru (I seek refuge with Allah and with His Power from the evil that afflicts me and that which I apprehend)."'[Muslim].

وعن أبي عبد الله عثمان بن أبي العاص رضي الله عنه أنه شكي إلي رسول الله صلى الله عليه وسلم وجعاً يجده في جسده فقال رسول الله صلى الله عليه وسلم ‏"‏ضع يدك علي الذي تألم من جسدك وقل‏:‏ بسم الله -ثلاثاً- وقل سبع مرات‏:‏ أعوذ بعزة الله وقدرته من شر ما أجد وأحاذر” ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
