Nothing has troubled my heart since I embraced Islam except this. I once recited a verse, and another man recited it differently from my recitation.I said, "The Messenger of Allah ﷺ taught me to recite it this way."The other said, "The Messenger of Allah ﷺ taught me to recite it this way."So I went to the Prophet ﷺ and said, "Prophet of Allah, did you teach me such-and-such verse?"He answered, "Yes."The other man said, "Did you not teach me such-and-such verse?"He answered, "Yes. Jibreel and Mikail, peace be upon them, came to me. Jibreel sat on my right and Mikail on my left. Jibreel said, 'Recite the Quran in one mode.' Mikail said, 'Ask for more, ask for more,' until it reached seven modes. Each mode is sufficient and complete."
ما حاك في صدري منذ أسلمت إلا أني قرأت آية وقرأها آخر غير قراءتي، فقلت: أقرأنيها رسول الله ﷺ وقال الآخر: أقرأنيها رسول الله ﷺ، فأتيت النبي ﷺ فقلت: يا نبي الله أقرأتني آية كذا وكذا؟ قال: نعم. وقال الآخر: ألم تقرئني آية كذا وكذا؟ قال: نعم، إن جبريل وميكائيل عليهما السلام أتياني فقعد جبريل عن يميني، وميكائيل عن يساري، فقال جبريل عليه السلام: اقرأ القرآن على حرف قال ميكائيل استزده استزده حتى بلغ سبعة أحرف، فكل حرف شاف كاف.
Nasai (941) narrated it from Yaqub bin Ibrahim, who said, Yahya narrated to us, from Humayd, from Anas, from Ubayy bin Kaab, and he related the hadith. He also narrated it in Fadail al-Quran (11), and Ahmad (21092, 21093) narrated it as well, both of them through the hadith of Humayd, from Anas, except that Ahmad, in the first instance, inserted Ubada bin Samit between Anas and Ubayy bin Kaab. Ibn Hibban graded it sahih (737).
