Muwatta Imam Malik Book of The Qur'an, Hadith 25
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 ﷺ when the Messenger of Allah ﷺ 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 ﷺ had finished, he said, 'Who was it who spoke just now?' The man said, 'I did, Messenger of Allah,' and the Messenger of Allah ﷺ 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 ﷺ فَلَمَّا رَفَعَ رَسُولُ اللَّهِ ﷺ رَأْسَهُ مِنَ الرَّكْعَةِ وَقَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . قَالَ رَجُلٌ وَرَاءَهُ رَبَّنَا وَلَكَ الْحَمْدُ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ . فَلَمَّا انْصَرَفَ رَسُولُ اللَّهِ ﷺ قَالَ " مَنِ الْمُتَكَلِّمُ آنِفًا " . فَقَالَ الرَّجُلُ أَنَا يَا رَسُولَ اللَّهِ . فَقَالَ رَسُولُ اللَّهِ ﷺ " لَقَدْ رَأَيْتُ بِضْعَةً وَثَلاَثِينَ مَلَكًا يَبْتَدِرُونَهَا أَيُّهُمْ يَكْتُبُهُنَّ أَوَّلاً " .
