I heard Hisham bin Hakim reciting Surat-al-Furqan during the lifetime of Allah's Messenger (ﷺ), I listened to his recitation and noticed that he was reciting in a way that Allah's Messenger (ﷺ) had not taught me. I was about to jump over him while He was still in prayer, but I waited patiently and when he finished his prayer, I put my sheet round his neck (and pulled him) and said, Who has taught you this Sura which I have heard you reciting? Hisham said, Allah's Messenger (ﷺ) taught it to me. I said, You are telling a lie, for he taught it to me in a way different from the way you have recited it! Then I started leading (dragged) him to Allah's Messenger (ﷺ) and said (to the Prophet), I have heard this man reciting Surat-al- Furqan in a way that you have not taught me. The Prophet (ﷺ) said: (O `Umar) release him! Recite, O Hisham. Hisham recited in the way I heard him reciting. Allah's Messenger (ﷺ) said, It was revealed like this. Then Allah's Messenger (ﷺ) said, Recite, O `Umar! I recited in the way he had taught me, whereupon he said, It was revealed like this, and added, The Qur'an has been revealed to be recited in seven different ways, so recite of it whichever is easy for you . (See Hadith No. 514, Vol. 6)

':'Telah menceritakan kepada kami Yahya bin Bukair telah menceritakan kepada kami Al Laits dari 'Uqail dari Ibn Syihab telah menceritakan kepadaku 'Urwah bahwa Miswar bin Makhramah dan Abdurrahman bin Abdul Qari keduanya menceritakan kepadanya bahwa ia mendengar Umar bin Khattab berkata 'Aku mendengar Hisyam bin Hakim membaca surat al Furqaan semasa Rasulullah shallallahu 'alaihi wasallam masih hidup dan aku menikmati bacaannya. Ternyata dia membaca dengan dialek yang berbeda-beda yang Rasulullah shallallahu 'alaihi wasallam belum pernah membacakannya kepadaku sehingga hampir saja aku menarik kepalanya ketika shalat. Namun aku berusaha menahan kesabaranku hingga ia mengucapkan salam lantas aku mengikatnya dengan pakaiannya dan aku tanyakan 'Siapa yang mula-mula membacakan surat Al Qur'an kepadamu yang aku dengar engkau membacanya? ' Ia menjawab 'Rasulullah shallallahu 'alaihi wasallam yang membacakannya kepadaku! Aku lalu berkata 'Engkau dusta sebab rasul membacakan kepadaku tidak seperti yang engkau baca.' Maka aku bawa Hisyam bin hakim kepada Rasulullah shallallahu 'alaihi wasallam dan aku laporkan 'Aku telah mendengar orang ini membaca surat Al Qur'an tidak dengan dialek seperti yang engkau bacakan kepadaku.' Kemudian Rasulullah berkata: 'Lepaskan dia bacalah ya Hisyam! ' Lantas Hisyam membaca bacaan yang sebelumnya aku mendengarnya kemudian Rasulullah shallallahu 'alaihi wasallam bersabda: 'Begitulah surat itu diturunkan! ' Lantas Rasulullah shallallahu 'alaihi wasallam bersabda: 'Bacalah wahai Umar! ' Aku pun membaca sebagaimana yang beliau bacakan kepadaku dan beliau juga berkomentar 'Begitulah surat Al Qur'an diturunkan sesungguhnya surat Al Qur'an ini diturunkan dengan tujuh dialek maka bacalah apa yang mudah bagimu'.''
