The Messenger of Allah ﷺ said, "The angels continue to invoke blessings upon any one of you as long as he remains in the place where he prayed, so long as he does not break his ablution or get up. They say, 'O Allah, forgive him. O Allah, have mercy on him.'"
حدثنا القعنبي عن مالك عن أبي الزناد عن الأعرج
أن رسول الله ﷺ قال الملائكة تصلي على أحدكم ما دام في مصلاه الذي صلى فيه ما لم يحدث أو يقم اللهم اغفر له اللهم ارحمه
Bukhari narrated it in "Prayer," the chapter on breaking wind in the masjid, hadith no. 445, from the hadith of Malik through this same chain, and it is also found in Muwatta (Yahya): 1/160 (and Qanabi, p. 106).
