The Prophet ﷺ said, "As long as the believing servant remains in his place of prayer, held there only by his waiting for the next prayer, the angels stay with him saying, 'Allah, have mercy on him. Allah, forgive him,' so long as he does not break his ablution."

عن النبي ﷺ قال إن العبد المؤمن ما دام في مصلاه لا يحبسه إلا انتظار الصلاة والملائكة معه تقول اللهم ارحمه اللهم اغفر له ما لم يحدث
