Abraham and Ishmael worked hard to rebuild the Kabah and as they did so they prayed to Allah to send a Prophet from among their descendants. And when Abraham and Ishmael were raising the foundations of the House, (Abraham prayed): Our Lord! Receive this from us; Thou, only Thou, art the All-hearing, the All-knowing; Our Lord! And make us submissive unto Thee and of our seed a nation submissive unto Thee, and show us our ways of worship, and turn toward us. Lo! Thou, only Thou, art the Relenting, the Merciful. Our Lord! And raise up in their midst a messenger from among them who shall recite unto them Thy revelations, and shall instruct them in the S*****ure and in wisdom and shall make them grow. Lo! Thou, only Thou, art the Mighty, Wise. (Koran ii.127-9) When the Kabah was completed, Allah commanded Abraham to call mankind to pilgrimage to His Holy House. Abraham wondered how anyone could hear his call. Allah said, You call and I will bring them. This was how the pilgrimage to the Kabah in Mecca was established and when Muslims make the pilgrimage today they continue to answer the age-old call of Abraham.
