Hadith 8121

وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " الْمَلَائِكَةُ تُصَلِّي عَلَى أَحَدِكُمْ مَا دَامَ فِي مُصَلَّاهُ الَّذِي صَلَّى فِيهِ مَا لَمْ يُحْدِثْ : اللَّهُمَّ اغْفِرْ لَهُ ، اللَّهُمَّ ارْحَمْهُ " .
And the Noble Prophet (peace and blessings be upon him) said: As long as a person waits for the prayer, he is counted as being in prayer, and the angels continue to supplicate for his forgiveness, saying: O Allah, forgive him, O Allah, have mercy on him, as long as he does not lose his ablution.
