His father said: "I prayed behind the Messenger of Allah ﷺ and when he said the takbir, he raised his hands to the bottom of his ears. When he recited: Not (the way) of those who earned Your anger, nor of those who went astray), he said: 'Amin,' and I could hear him although I was behind him. The Messenger of Allah ﷺ heard a man saying: 'Al-hamdu lillahi, hamdan kathiran tayiban mubarakan fih, (Praise be to Allah, much good and blessed praise.)' When the Prophet ﷺ said the salam and finished his prayer, he said: 'Who spoke those words during the prayer?' The man said: 'I did, O Messenger of Allah, but I did not mean anything bad thereby.' The Prophet ﷺ said: "Twelve angels hastened (to take it) and nothing is stopping it going all the way to the Throne.'" (Using translation from Nasāʾī 932)  

صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ فَلَمَّا كَبَّرَ رَفَعَ يَدَيْهِ أَسْفَلَ مِنْ أُذُنَيْهِ فَلَمَّا قَرَأَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] قَالَ «آمِينَ» فَسَمِعْتُهُ وَأَنَا خَلْفَهُ قَالَ فَسَمِعَ رَسُولُ اللهِ ﷺ رَجُلًا يَقُولُ الْحَمْدُ لِلَّهِ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ فَلَمَّا سَلَّمَ النَّبِيُّ ﷺ مِنْ صَلَاتِهِ قَالَ «مَنْ صَاحِبُ الْكَلِمَةِ فِي الصَّلَاةِ؟» قَالَ الرَّجُلُ أَنَا يَا رَسُولَ اللهِ وَمَا أَرَدْتُ بِهَا بَأَسًا قَالَ النَّبِيُّ ﷺ «لَقَدِ ابْتَدَرَهَا اثْنَا عَشَرَ مَلَكًا فَمَا نَهْنَهَهَا شَيْءٌ دُونَ الْعَرْشِ»
