I'm reading Sura 19, Maryam, and while I've always been familiar of the birth narrative of Isa, I never pondered how the Qur'an reconciles the immaculate conception of Maryam & miraculous birth of Isa. Of course, Islam does not believe that Isa is the son of God, but who then is Isa's father?
Isa's identifying title as "son of Mary," places unconventional emphasis on Mary's motherhood because for both texts and cultures at this time, individuals were identified by their male relatives. So does the Quran and its commentators not have any statement on who Isa's father is? Indeed it was miraculous, but how/why would Isa be born without a father?
