Umar bin al-Khattab said: I heard Hisham bin Hakim (b. Hizam) reciting Surah al-Furqan in a different manner from my way of reciting, and the Messenger of Allah ﷺ had taught me to recite it. I nearly spoke sharply to him, but I delayed till he had finished. Then I caught his cloak at the neck, and I brought him to the Messenger of Allah ﷺ. I said: Messenger of Allah, I heard this man reciting Surah al-Furqan in a manner different from that in which you taught me to recite it. The Messenger of Allah ﷺ the told him to recite it. He then recited in the manner I heard him recite. The Messenger of Allah ﷺ said: Thus was it sent down. He then said to me: Recite, I recited (it). He then said: Thus was it sent down. He said: The Quran was sent down in seven modes of reading, so recite according to what comes most easily.

Ubayy bin Kab reported: The Prophet ﷺ said: "Ubayy, I was asked to recite the Quran and I was asked: 'In one mode or two modes?' The angel that accompanied me said: 'Say, in two modes', I said: 'In two modes', I was asked again: 'In two or three modes'. The matter reached up to seven modes. He then said: 'Each mode is sufficiently health-giving, whether you utter 'all-hearing and all-knowing' or instead 'all-powerful and all-wise'. This is valid until you finish the verse indicating punishment on mercy and finish the verse indicating mercy on punishment. "

Ubayy bin Kab said: The Prophet ﷺ was present at the pool of Banu Ghifar, Gabriel came to him and said: "Allah has commanded you to make your community read (the Quran) in one harf.
