These events were an important part of Allah's plan, for the descendants of Ishmael would form a nation from which would come a great Prophet, who would guide the people in the way of Allah. This was to be Muhammad (pbuh), the Messenger of Allah (pbuh). From the descendants of Sarah's child, Isaac, would come Moses and Jesus.
So it was that Abraham, Hagar, and Ishmael left Palestine. They traveled for many days until finally they reached the arid valley of Bacca ( later to be called Mecca), which was on one of the great caravan routes. There was no water in the valley and although Hagar and Ishmael only had a small supply of water left, Abraham left them there knowing Allah would take care of them. Soon all the water was gone. The child began to grow weak from thirst. There were two hills nearby, one called Safa and the other Marwah. Hagar went up one hill and looked into the distance to see if she could find any water,

but found none. So she went to the other hill and did the same. She did this seven times. Then sadly she returned to her son, and to her great surprise and joy she found a spring of water bubbling out of the earth near him. This spring, near which the mother and child settled, was later called Zamzam. The area around it became a place of rest for the caravans travelling across the desert and in time grew into the famous trading city of Mecca.
From time to time Abraham traveled from Palestine to visit his family and he saw Ishmael grow into a strong young man. It was during one of these visits that Allah commanded them to rebuild the Ka'bah-the very first place where people had worshipped Allah. They were told exactly where and how to build it. It was to be erected by the well of Zamzam and built in the shape of a cube. In its eastern corner was to be placed a black stone that had fallen to earth from heaven. An angel brought the stone to them from the nearby hill of Abu Qubays.
Abraham and Ishmael worked hard to rebuild the Ka'bah 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 ******ure and in wisdom and shall make them grow. Lo! Thou, only Thou, art the Mighty, Wise. (Koran ii.127-9) When the Ka'bah 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 Ka'bah in Mecca was established and when Muslims make the pilgrimage today they continue to answer the age-old call of Abraham.
