What did Umar (peace be upon him) hear Hisham (peace be upon him) reciting during the lifetime of the Prophet Muhammad (saw)?
 This hadith has been transmitted thus by 'Umar b. Khattab (with a slight change of words):                     " I heard Hisham b. Hakim reciting Surah al-Furqan during the lifetime of Allah's Messenger (may peace be upon him)." The rest is the same but with this addition:" I was about to catch hold of him in prayer, but I exercised patience till he pronounced salutation.
