Musnad `Umar b. al-Khattab (ra)
Musnad Ahmad 296, 297
It was narrated from al Miswar bin Makhrarnah 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 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.

حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَنْبَأَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنِ الْمِسْوَرِ بْنِ مَخْرَمَةَ، وَعَبْدِ الرَّحْمَنِ بْنِ عَبْدٍ الْقَارِيِّ، أَنَّهُمَا سَمِعَا عُمَرَ، رَضِيَ اللَّهُ عَنْهُ يَقُولُ مَرَرْتُ بِهِشَامِ بْنِ حَكِيمِ بْنِ حِزَامٍ يَقْرَأُ سُورَةَ الْفُرْقَانِ فِي حَيَاةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَمَعْتُ قِرَاءَتَهُ فَإِذَا هُوَ يَقْرَأُ عَلَى حُرُوفٍ كَثِيرَةٍ لَمْ يُقْرِئْنِيهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَكِدْتُ أَنْ أُسَاوِرَهُ فِي الصَّلَاةِ فَنَظَرْتُ حَتَّى سَلَّمَ فَلَمَّا سَلَّمَ لَبَّبْتُهُ بِرِدَائِهِ فَقُلْتُ مَنْ أَقْرَأَكَ هَذِهِ السُّورَةَ الَّتِي تَقْرَؤُهَا قَالَ أَقْرَأَنِيهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ قُلْتُ لَهُ كَذَبْتَ فَوَاللَّهِ إِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَهُوَ أَقْرَأَنِي هَذِهِ السُّورَةَ الَّتِي تَقْرَؤُهَا قَالَ فَانْطَلَقْتُ أَقُودُهُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنِّي سَمِعْتُ هَذَا يَقْرَأُ سُورَةَ الْفُرْقَانِ عَلَى حُرُوفٍ لَمْ تُقْرِئْنِيهَا وَأَنْتَ أَقْرَأْتَنِي سُورَةَ الْفُرْقَانِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَرْسِلْهُ يَا عُمَرُ اقْرَأْ يَا هِشَامُ فَقَرَأَ عَلَيْهِ الْقِرَاءَةَ الَّتِي سَمِعْتُهُ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ هَكَذَا أُنْزِلَتْ ثُمَّ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اقْرَأْ يَا عُمَرُ فَقَرَأْتُ الْقِرَاءَةَ الَّتِي أَقْرَأَنِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ هَكَذَا أُنْزِلَتْ ثُمَّ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ الْقُرْآنَ أُنْزِلَ عَلَى سَبْعَةِ أَحْرُفٍ فَاقْرَءُوا مِنْهُ مَا تَيَسَّرَ

حَدَّثَنَا الْحَكَمُ بْنُ نَافِعٍ أَنْبَأَنَا شُعَيْبٌ عَنِ الزُّهْرِيِّ حَدَّثَنِي عُرْوَةُ عَنْ حَدِيثِ الْمِسْوَرِ بْنِ مَخْرَمَةَ وَعَبْدِ الرَّحْمَنِ بْنِ عَبْدٍ الْقَارِيِّ أَنَّهُمَا سَمِعَا عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ يَقُولُ سَمِعْتُ هِشَامَ بْنَ حَكِيمِ بْنِ حِزَامٍ يَقْرَأُ سُورَةَ الْفُرْقَانِ فِي حَيَاةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَاسْتَمَعْتُ لِقِرَاءَتِهِ فَإِذَا هُوَ يَقْرَأُ عَلَى حُرُوفٍ كَثِيرَةٍ لَمْ يُقْرِئْنِيهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَكِدْتُ أُسَاوِرُهُ فِي الصَّلَاةِ فَنَظَرْتُ حَتَّى سَلَّمَ فَلَمَّا سَلَّمَ فَذَكَرَ مَعْنَاهُ‏.‏
