I heard Hisham bin Hakeem reciting Sooratul-Furqan in prayer in a manner other than I recited it, and the Messenger of Allah ﷺ had taught it to me. I caught him by his garment and brought him to the Messenger of Allah ﷺ , and said: O Messenger of Allah ﷺ, I heard this man reciting Sooratul Furqan in a manner other than you taught it to me. The Messenger of Allah ﷺ said: ʿRecite it.” He recited it in the manner in which I had heard him recite, and the Messenger of Allah ﷺ said: ʿThus it was revealed.” Then he said to me: ʿRecite it.” So I recited it and he said: “Thus it was revealed. This Qurʿan has been revealed in seven modes of recitation, so recite whatever is easy for you.ʿ It was narrated that al Miswar bin Makhramah and ʿAbdur-Rahman bin Abdul-Qari heard ‘Umar say: I passed by Hisham bin Hakeem bin Hizam when he was reciting Sooratul Furqan... and he mentioned a similar hadeeth.
سَمِعْتُ هِشَامَ بْنَ حَكِيمٍ يَقْرَأُ سُورَةَ الْفُرْقَانِ فِي الصَّلاةِ عَلَى غَيْرِ مَا أَقْرَؤُهَا وَكَانَ رَسُولُ اللهِ ﷺ أَقْرَأَنِيهَا فَأَخَذْتُ بِثَوْبِهِ فَذَهَبْتُ بِهِ إِلَى رَسُولِ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي سَمِعْتُهُ يَقْرَأُ سُورَةَ الْفُرْقَانِ عَلَى غَيْرِ مَا أَقْرَأْتَنِيهَا فَقَالَ اقْرَأْ فَقَرَأَ الْقِرَاءَةَ الَّتِي سَمِعْتُهَا مِنْهُ فَقَالَ هَكَذَا أُنْزِلَتْ ثُمَّ قَالَ لِي اقْرَأْ فَقَرَأْتُ فَقَالَ هَكَذَا أُنْزِلَتْ إِنَّ هَذَا الْقُرْآنَ أُنْزِلَ عَلَى سَبْعَةِ أَحْرُفٍ فَاقْرَءُوا مَا تَيَسَّرَ
