abraham, for surrogacy. >> suns she had given birth to a boy ismail, sarah told them she wanted both of them out for good. >> you see hagar's extreme distre distress, and then god appears to her and said fear not, from this child, i will also make a people, and this is the arab people. >> arabs today trace their lineage right back to abraham through ismy el. each year, millions of christians make their pilgrimage to the place where they believe abraham made his home. here, muslims also believe abraham came to visit ismael and they built the first house of worship. the bible doesn't mention mecca. instead, it tells us abraham finally found a permanent home in kanaan.
