Hazrat Yahya bin Saeed (may Allah have mercy on him) says that someone mentioned before Hazrat Qasim (may Allah have mercy on him) that Abdul Malik bin Marwan (may Allah have mercy on him) separated men from such wives who were umm walad (slave women who bore children to their masters) of their masters. But after one or two menstrual cycles, their marriages were conducted. Abdul Malik bin Marwan (may Allah have mercy on him) ordered that they should observe an 'iddah of four months and ten days. Upon hearing this, Hazrat Qasim (may Allah have mercy on him) said, "Subhan Allah! Allah Almighty says in the Holy Qur'an { وَالَّذِینَ یُتَوَفَّوْنَ مِنْکُمْ وَیَذَرُونَ أَزْوَاجًا } so are these masters their husbands?"
