Abu Ishaq narrates: I heard a man asking Aswad bin Yazid while he was teaching the Qur'an in the mosque. (The question was) How do you recite this verse? « فَهَلْمِنْمُدَّكِرٍ » Do you recite it with "dal" or with "dhal"? He replied: I recite it with "dal" because I heard Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) stating this. The Prophet Muhammad (peace be upon him) recited «فَهَلْمِنْمُدَّكِرٍ» that is, he recited it with "dal".
