Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him) said: I heard Hisham ibn Hakim (may Allah be pleased with him) reciting Surah al-Furqan in a way that I did not recite it, and the Messenger of Allah (peace and blessings of Allah be upon him) had taught me this Surah. I was about to attack him in haste, but I gave him respite. When he finished (his recitation), I wrapped his cloak around his neck and took him to the Messenger of Allah (peace and blessings of Allah be upon him). Then I said: O Messenger of Allah! I heard him (Hisham) reciting Surah al-Furqan in a manner different from the way you taught me. The Messenger of Allah (peace and blessings of Allah be upon him) said to Hisham: "Recite!" So he recited as I had heard him. Then the Prophet (peace and blessings of Allah be upon him) said: "It was revealed in this way." Then he said to me: "Recite!" So I recited (the Surah), and he said: "It was revealed in this way." This Qur'an has been revealed upon seven modes (of recitation), so recite whatever is easy for you from it.
