Ibn 'Umar reported:
حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ ، أَخْبَرَنِي الْحَجَّاجُ بْنُ أَبِي عُثْمَانَ ، عَنْ أَبِي الزُّبَيْرِ ، عَنْ عَوْنِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ ، عَنِ ابْنِ عُمَرَ ، قَالَ بَيْنَمَا نَحْنُ نُصَلِّي مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِذْ قَالَ رَجُلٌ مِنَ الْقَوْمِ اللَّهُ أَكْبَرُ كَبِيرًا وَالْحَمْدُ لِلَّهِ كَثِيرًا وَسُبْحَانَ اللَّهِ بُكْرَةً وَأَصِيلاً . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " 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 صلى الله عليه وسلم يَقُولُ ذَلِكَ .
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.
