A man came panting to join the row of worshippers, and said: Allah is most great; praise be to Allah, much praise, good and blessed. When the Messenger of Allah ﷺ finished his prayer, he asked: Which of you is the one who spoke the words? He said nothing wrong. Then the man said: I (said), Messenger of Allah ﷺ; I came and had difficulty in breathing, so I said them. He said: I saw twelve angels racing against one another to be the one to take them to Allah. The narrator Humaid added: When any of you comes for praying, he should walk as usual (i.e. he should not hasten and run quickly); then he should pray as much as he finds it (along with the imam), and should offer the part of the prayer himself (when the prayer is finished) which the Imam had offered before him. (Using translation from Abū Dāʾūd 763)
أَنَّ رَجُلًا جَاءَ فَدَخَلَ الصَّفَّ وَقَدْ حَفَزَهُ النَّفَسُ فَقَالَ الْحَمْدُ لِلَّهِ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ فَلَمَّا قَضَى رَسُولُ اللهِ ﷺ صَلَاتَهُ قَالَ أَيُّكُمُ الْمُتَكَلِّمُ بِالْكَلِمَاتِ؟ فَأَرَمَّ الْقَوْمُ فَقَالَ أَيُّكُمُ الْمُتَكَلِّمُ بِهَا؟ فَإِنَّهُ لَمْ يَقُلْ إِلَّا خَيْرًا فَقَالَ الرَّجُلُ جِئْتُ وَقَدْ حَفَزَنِي النَّفَسُ فَقُلْتُهَا فَقَالَ لَقَدْ رَأَيْتُ اثْنَيْ عَشَرَ مَلَكًا يَبْتَدِرُونَهَا أَيُّهُمْ يَرْفَعُهَا وَزَادَ حُمَيْدٌ عَنْ أَنَسٍ أَنَّ رَسُولَ اللهِ ﷺ قَالَ إِذَا جَاءَ أَحَدُكُمْ فَلْيَمْشِ عَلَى نَحْوِ مَا كَانَ يَمْشِي فَلْيُصَلِّ مَا أَدْرَكَوَلْيَقْضِ مَا سَبَقَهُ قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَالْإِرْمَامُ السُّكُوتُ
