“If you are Abraham’s children, do the deeds of Abraham.” (Jesus, John; 8:39)
” So you see that it is men of faith who are the sons of Abraham.”(Galatians;3:6-7),
Prophet Abraham (peace be upon him) was successful in the trial, he was childless, he was granted sons at old age, Ishmael, from his second wife Hager, and later Isaac (Ishaq) from his first wife Sara. According to an Islamic tradition he left Ishmael at Makka while he was older enough. The other tradition narrates that he had to leave the infant Isma’il and his mother at a far off place in desert (Makka). They miraculously survived due to water of spring (Zamzam). Abraham's faith was so great that later he went to obey God's command to sacrifice his only son (Ishmael), however at the last minute; God permitted him to substitute a ram. Muslim tradition identifies the son to be sacrificed as Ishmael (Biblical traditions claim, Isaac). Prophet Abraham (peace be upon him) again came to Makka to rebuilt the first house of Allah, Ka’ba with Isma’il as a sign of God's covenant with them and established the rituals of pilgrimage (Hajj). Allah says: “And when Abraham and Ishmael were raising the foundations of the House, (Abraham prayed): Our Lord! Accept from us (this duty). Lo! Thou, only Thou, art the Hearer, the Knower.”(Qur’an;2:127).
