Ishaq is reported to have said on the authority of Aswad who quoted on the authority of 'Abdullah b. Mas'ud that the Messenger of Allah ﷺ used to recite these words as (fahal min muddakir). (Using translation from Muslim 823b)
عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَقْرَأُ هَذَا الْحَرْفَ {هَلْ مِنْ مُدَّكِرٍ}
