"I had no confusion in my mind from that time I embraced Islam, except when I recited a verse and another man recited it differently. I said: 'The Messenger of Allah ﷺ taught me this.' And the other man said: 'The Messenger of Allah ﷺ taught me too.' So I went to the Prophet ﷺ and said: 'O Prophet of Allah, did you not teach me such and such a verse?' He said: 'Yes.' The other man said: 'Did you not teach me such and such a verse?' He said: 'Yes. Jibril and Mika'il, peace be upon them, came to me, and Jibril sat on my right and Mika'il on my left. Jibril, peace be upon him, said: "Recite the Quran with one way of recitation.' Mika'il said: 'Teach him more, teach him more- until there were seven modes of recitation, each of which is good and sound.'" (Using translation from Nasāʾī 941)
مَا حَكَّ فِي صَدْرِي شَيْءٌ مُنْذُ أَسْلَمْتُ إِلَّا أَنِّي قَرَأْتُ آيَةً وَقَرَأَهَا رَجُلٌ غَيْرَ قِرَاءَتِي فَأَتَيْنَا النَّبِيَّ ﷺ قَالَ قُلْتُ أَقْرَأْتَنِي آيَةَ كَذَا وَكَذَا؟ قَالَ نَعَمْ قَالَ فَقَالَ الْآخَرُ أَلَمْ تُقْرِئْنِي آيَةَ كَذَا وَكَذَا؟ قَالَ نَعَمْ أَتَانِي جِبْرِيلُ (3 وَمِيكَائِيلُ فَقَعَدَ جِبْرِيلُ 3) عَنْ يَمِينِي وَمِيكَائِيلُ عَنْ يَسَارِي فَقَالَ جِبْرِيلُ اقْرَأِ الْقُرْآنَ عَلَى حَرْفٍ فَقَالَ مِيكَائِيلُاسْتَزِدْهُ حَتَّى بَلَغَ سَبْعَةَ أَحْرُفٍ كُلُّهَا شَافٍ كَافٍ
