Chapter: The Quran was revealed to be recited in seven different ways

Allah's Messenger (ﷺ) said, "Gabriel recited the Qur'an to me in one way. Then I requested him (to read it in another way), and continued asking him to recite it in other ways, and he recited it in several ways till he ultimately recited it in seven different ways."

I heard Hisham bin Hakim reciting Surat Al-Furqan during the lifetime of Allah's Messenger (ﷺ) and I listened to his recitation and noticed that he recited in several different ways which Allah's Messenger (ﷺ) had not taught me. I was about to jump over him during his prayer, but I controlled my temper, and when he had completed his prayer, I put his upper garment around his neck and seized him by it and said, "Who taught you this Sura which I heard you reciting?" He replied, "Allah's Messenger (ﷺ) taught it to me." I said, "You have told a lie, for Allah's Messenger (ﷺ) has taught it to me in a different way from yours." So I dragged him to Allah's Messenger (ﷺ) and said (to Allah's Messenger (ﷺ)), "I heard this person reciting Surat Al-Furqan in a way which you haven't taught me!" On that Allah's Apostle said, "Release him, (O `Umar!) Recite, O Hisham!" Then he recited in the same way as I heard him reciting. Then Allah's Messenger (ﷺ) said, "It was revealed in this way," and added, "Recite, O `Umar!" I recited it as he had taught me. Allah's Messenger (ﷺ) then said, "It was revealed in this way. This Qur'an has been revealed to be recited in seven different ways, so recite of it whichever (way) is easier for you (or read as much of it as may be easy for you).
