[Pooya/Ali Commentary 36:6] The heathens of Makka, after prophet Ibrahim had not received any messenger of Allah. Aqa Mahdi Puya says: . This verse refers to the people of his immediate audience who are supposed to be the descendants of Ibrahim through Ismail, similar to "warn your relatives" in Shu-ara: 214. However, it does not mean that the Holy Prophet's mission was only for those particular people. It is a universal mission as said in Araf: 158. Though after Ismail all the direct ancestors of the Holy Prophet followed the religion of Ibrahim (Islam) none among them was appointed a prophet.
