Muwatta Malik, Book 15, Hadith 25 (USC-MSA) ⓘ

Malik related to me from Nuaym ibn Abdullah ibn al-Mujmir from AIi ibn Yahya az-Zuraqi from his father that Rifaa ibn Rafi said, "One day we were praying behind the Messenger of Allah, may Allah bless him and grant him peace, when the Messenger of Allah, may Allah bless him and grant him peace, raised his head from ruku and said, 'Allah hears the one who praises Him' (Sami Allahu liman hamidah). A man behind him said, 'Our Lord, praise belongs to you - blessed, pure and abundant praise' (Rabbana wa laka'l hamd, hamdan kathiran tayiban mubarakan fihi). When the Messenger of Allah, may Allah bless him and grant him peace, had finished, he said, 'Who was it who spoke just now?' The man said, 'I did, Messenger of Allah,' and the Messenger of Allah, may Allah bless him and grant him peace, said, 'I saw more than thirty angels rushing to it to see which one of them would record it first.' "

وَحَدَّثَنِي مَالِكٌ، عَنْ نُعَيْمِ بْنِ عَبْدِ اللَّهِ الْمُجْمِرِ، عَنْ عَلِيِّ بْنِ يَحْيَى الزُّرَقِيِّ، عَنْ أَبِيهِ، عَنْ رِفَاعَةَ بْنِ رَافِعٍ، أَنَّهُ قَالَ كُنَّا يَوْمًا نُصَلِّي وَرَاءَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَلَمَّا رَفَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم رَأْسَهُ مِنَ الرَّكْعَةِ وَقَالَ ‏"‏ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ‏"‏ ‏.‏ قَالَ رَجُلٌ وَرَاءَهُ رَبَّنَا وَلَكَ الْحَمْدُ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ ‏.‏ فَلَمَّا انْصَرَفَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَنِ الْمُتَكَلِّمُ آنِفًا ‏"‏ ‏.‏ فَقَالَ الرَّجُلُ أَنَا يَا رَسُولَ اللَّهِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ لَقَدْ رَأَيْتُ بِضْعَةً وَثَلاَثِينَ مَلَكًا يَبْتَدِرُونَهَا أَيُّهُمْ يَكْتُبُهُنَّ أَوَّلاً ‏"‏ ‏.‏
