I passed by Hisham bin Hakeem bin Hizam when he was reciting Sooratal-Furqan during the lifetime of the Messenger of Allah (ﷺ), I listened to his recitation and he was reciting in a manner different from the way in which the Messenger of Allah (ﷺ) had taught me to recite it. I was about to interrupt him whilst he was praying, but I waited until he finished his prayer, and then I tied his garment around his neck. I said to him: Who taught you this soorah that you are reciting? He said: The Messenger of Allah (ﷺ) taught it to me. I said to him: You are lying by Allah! He taught me this soorah that you recited. I brought him to the Messenger of Allah (ﷺ) and said, `O Messenger of Allah (ﷺ), I heard this man reciting Sooratal-Furqan in a way different to the way you taught it to me, and you taught me Sooratal-Furqan, The Prophet (ﷺ) said: Let him go, O `Umar: Recite it, O Hisham. So he recited it to him as I had heard him recite it. The Messenger of Allah (ﷺ) said, `Thus it was revealed.` Then he said to me, `Recite it,” so I recited it and he said, “Thus it was revealed.` Then the Messenger of Allah (ﷺ) is said: `This Qur`an has been revealed in seven different ways, so recite it in the way that is easiest for you.”

It was narrated from al Miswar bin Makhramah and `Abdur-Rahman bin Abdul-Qari that they heard Umar bin al Khattab say: I passed by Hisham bin Hakeem bin Hizam when he was reciting Sooratal-Furqan during the lifetime of the Messenger of Allah (ﷺ). I listened to his recitation and he was reciting in a way different from the way in which the Messenger of Allah (ﷺ) had taught me to recite it. I was about to interrupt him whilst he was praying, but I waited until he said the tasleem, and when he had said the tasleem,... and he narrated a similar report.
