ذِكْرُ اسْتِحْبَابِ الِاجْتِهَادِ لِلْمَرْءِ فِي الْحَمْدِ لِلَّهِ بَعْدَ رَفْعِ رَأْسِهِ مِنَ الرُّكُوعِ
One day we were praying behind the Messenger of Allah ﷺ. When the Messenger of Allah ﷺ raised his head after bowing, he said: Allah listened to him who praised Him. A man behind the Messenger of Allah ﷺ said: O Allah, Our Lord, and to Thee be praise, much praise, good and blessed. When the Messenger of Allah ﷺ finished his prayer, he asked: Which of you if the one who spoke (the words) just now. The man said: I (uttered) these words, Prophet of Allah. The Messenger of Allah ﷺ said: I saw more than thirty angels racing against one another to be the one to write them first. (Using translation from Abū Dāʾūd 770)
كُنَّا يَوْمًا نُصَلِّي وَرَاءَ رَسُولِ اللَّهِ ﷺ فَلَمَّا رَفَعَ 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 رَجُلٌ أَنَا يَا رَسُولَ اللَّهِ فَقَالَ رَسُولُ اللَّهِ ﷺ «لَقَدْ رَأَيْتُ بِضْعًا وَثَلَاثِينَ مَلَكًا يَبْتَدِرُونَهَا أَيُّهُمْ يَكْتُبُهَا أَوَّلُ»
