While we said prayer with the Messenger of Allah ﷺ, one among the people said: Allah is truly Great, praise be to Allah in abundance. Glory be to Allah in the morning and the evening. The Messenger of Allah (may peace be upon, him) said: Who uttered such and such a word? A person among the people said: It is I, Messenger of Allah (who have recited these words). He (the Holy Prophet) said: It (its utterance) surprised me, for the doors of heaven were opened for It. Ibn 'Umar said: I have not abandoned them (these words) since I heard the Messenger of Allah ﷺ saying this.
بَيْنَمَا نَحْنُ نُصَلِّي مَعَ رَسُولِ اللَّهِ ﷺ إِذْ قَالَ رَجُلٌ مِنَ الْقَوْمِ: (اللَّهُ أَكْبَرُ كَبِيرًا، وَالْحَمْدُ لِلَّهِ كَثِيرًا، وَسُبْحَانَ اللَّهِ بُكْرَةً وَأَصِيلاً) فَقَالَ رَسُولُ اللَّهِ ﷺ: «مَنِ الْقَائِلُ كَلِمَةَ» كَذَا وَكَذَا؟ قَالَ رَجُلٌ مِنَ الْقَوْمِ: أَنَا يَا رَسُولَ اللَّهِ! قَالَ: «عَجِبْتُ لَهَا فُتِحَتْ لَهَا أَبْوَابُ السَّمَاءِ۔» قَالَ ابْنُ عُمَرَ فَمَا تَرَكْتُهُنَّ مُنْذُ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ ذَلِكَ۔
