Riyad as-Salihin, Book 9, Hadith 1062 (In-Book) ⓘ
Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah said, "The angels supplicate in favour of one of you so long as he remains in the place where he has performed Salat (prayer) in a state of Wudu'. They (the angels) say: 'O Allah! Forgive him, O Allah! Have mercy on him."'[Al- Bukhari].
وعنه أن رسول الله صلى الله عليه وسلم قال: الملائكة تصلي على أحدكم ما دام في مصلاه الذي صلى فيه ما لم يحدث تقول اللهم اغفر له اللهم ارحمه" ((رواه البخاري))
