I heard Hishām ibn Ḥakīm b. Ḥizām recite Sūrat al-Furqān in the life of the Prophet ﷺ. I sought to hear his recitation as he used to recite it with a lot of ḥurūf (variant readings) that the Messenger of Allah ﷺ did not recite to me. I almost intended to stop him in the prayer but I waited until he did taslīm. When he did taslīm... then ˹the narrator˺ mentioned ˹the rest of the ḥadīth˺ by meaning.  

سَمِعْتُ هِشَامَ بْنَ حَكِيمِ بْنِ حِزَامٍ يَقْرَأُ سُورَةَ الْفُرْقَانِ فِي حَيَاةِ النَّبِيِّ ﷺ فَاسْتَمَعْتُ لِقِرَاءَتِهِ فَإِذَا هُوَ يَقْرَأُ عَلَى حُرُوفٍ كَثِيرَةٍ لَمْ يُقْرِئْنِيهَا رَسُولُ اللهِ ﷺ فَكِدْتُ أُسَاوِرُهُ فِي الصَّلاةِ فَنَظَرْتُ حَتَّى سَلَّمَ فَلَمَّا سَلَّمَ فَذَكَرَ مَعْنَاهُ
