Congregational prayer for the sake of God elevates one by degrees, and for whom Angels continue to supplicate

The Messenger of Allah ﷺ said, "The reward for prayer performed by a person in congregation is more than twenty times greater than that of the prayer performed in one’s house or the marketplace. When one performs wuḍūʾ perfectly and then proceeds to the mosque with the sole intention of performing prayer, then for every step he takes towards the mosque, he is upgraded one degree in reward and one of his sins is eliminated until he enters the mosque."

"And when he enters the mosque, he is considered as performing prayer as long as it is the prayer which stops him ˹from leaving the mosque˺; and the angels keep on supplicating Allah for him as long as he remains in his place of prayer. They say: ‘O Allah! Have mercy on him; O Allah! forgive his sins; O Allah! accept his repentance.' ˹This continues, so long as he does cause harm ˹upon anyone˺ in it, or pass wind in it ˹breaking his wuḍūʾ˺ (in a different wording: or speak ˹to anyone˺).”  

قَالَ رَسُولُ اللَّهِ ﷺ: «صَلاَةُ الرَّجُلِ فِي جَمَاعَةٍ تَزِيدُ عَلَى صَلاَتِهِ فِي بَيْتِهِ وَصَلاَتِهِ فِي سُوقِهِ بِضْعًا وَعِشْرِينَ دَرَجَةً، وَذَلِكَ أَنَّ أَحَدَهُمْ إِذَا تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ، ثُمَّ أَتَى الْمَسْجِدَ لاَ يَنْهَزُهُ إِلاَّ الصَّلاَةُ لاَ يُرِيدُ إِلاَّ الصَّلاَةَ، فَلَمْ يَخْطُ خَطْوَةً إِلاَّ رُفِعَ لَهُ بِهَا دَرَجَةٌ وَحُطَّ عَنْهُ بِهَا خَطِيئَةٌ، حَتَّى يَدْخُلَ الْمَسْجِدَ۔»

«فَإِذَا دَخَلَ الْمَسْجِدَ كَانَ فِي الصَّلاَةِ مَا كَانَتِ الصَّلاَةُ هِيَ تَحْبِسُهُ وَالْمَلاَئِكَةُ يُصَلُّونَ عَلَى أَحَدِكُمْ مَا دَامَ فِي مَجْلِسِهِ الَّذِي صَلَّى فِيهِ، يَقُولُونَ اللَّهُمَّ ارْحَمْهُ، اللَّهُمَّ اغْفِرْ لَهُ، اللَّهُمَّ تُبْ عَلَيْهِ، مَا لَمْ يُؤْذِ فِيهِ مَا لَمْ يُحْدِثْ فِيهِ۔»  

A hadith having the same meaning (as mentioned above) has been transmitted by A'mash.  

عَنِ الأَعْمَشِ فِي هَذَا الإِسْنَادِ بِمِثْلِ مَعْنَاهُ  

The angels invoke blessings on everyone among you so long as he is in a place of worship with these words: O Allah! pardon him, O Allah, have mercy upon him, (and they continue to do so) as long as, he ablution (of the worshipper) is not broken, and one among you is in prayer and so long as he is detained for the prayer.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ الْمَلاَئِكَةَ تُصَلِّي عَلَى أَحَدِكُمْ مَا دَامَ فِي مَجْلِسِهِ تَقُولُ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ مَا لَمْ يُحْدِثْ وَأَحَدُكُمْ فِي صَلاَةٍ مَا كَانَتِ الصَّلاَةُ تَحْبِسُهُ  

The servant is constantly in prayer so long as he is in a place of worship waiting for the prayer (to be observed in congregation), and the angels invoke (blessings upon him in these words): O Allah! pardon him. O Allah! show mercy to him, (and they continue to do so) till he returns (from the mosque having completed the prayer) or his ablution breaks. I said: How is the ablution broken? He said: By breaking of the wind noiselessly or with noise.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَزَالُ الْعَبْدُ فِي صَلاَةٍ مَا كَانَ فِي مُصَلاَّهُ يَنْتَظِرُ الصَّلاَةَ وَتَقُولُ الْمَلاَئِكَةُ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ حَتَّى يَنْصَرِفَ أَوْ يُحْدِثَ قُلْتُ مَا يُحْدِثُ قَالَ يَفْسُو أَوْ يَضْرِطُ  

Everyone among you is constantly in prayer so long as the prayer detains him (for this noble objective) and nothing prevents him to return to his family but the prayer.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَزَالُ أَحَدُكُمْ فِي صَلاَةٍ مَا دَامَتِ الصَّلاَةُ تَحْبِسُهُ لاَ يَمْنَعُهُ أَنْ يَنْقَلِبَ إِلَى أَهْلِهِ إِلاَّ الصَّلاَةُ  

The Messenger of Allah ﷺ said: Anyone amongst you who sat in a place of worship waiting for the prayer is in prayer and his ablution is not broken, the angels invoke blessing upon him (in these words): O Allah! pardon him. O Allah! have mercy upon him.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ أَحَدُكُمْ مَا قَعَدَ يَنْتَظِرُ الصَّلاَةَ فِي صَلاَةٍ مَا لَمْ يُحْدِثْ تَدْعُو لَهُ الْمَلاَئِكَةُ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ  

A hadith like this has been narrated by Hammam b. Munabbih on the authority of Abu Huraira.  

عَنِ النَّبِيِّ ﷺ بِنَحْوِ هَذَا
