Nubayh ibn Wahb reported that Ibn Ma’mar decided to have his son married. So, he sent Nubayh to the amir of the pilgrimage Aban ibn Uthman (RA). He went to him and said, ‘Your brother intends to have his son married and that you should witness the solemnising.’ He said, ‘I find him not but illiterate. Neither does a pilgrim in the state of ihram marry nor have anyone married.’ (Or, as he said). Then he narrated from Uthman like that a marfu hadith.
