The Messenger of Allah ﷺ said, "The angels keep praying for one of you as long as he remains in the place where he prayed, so long as he does not break his ablution. They say, 'Allah, forgive him. Allah, have mercy on him.'"
و حدثني يحيى 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 اللهم اغفر له اللهم ارحمه.
