Prophet Abraham (Ibrahim) & Prophet Isaac (Ishaq A.S.)

The Well of Zamzam where water first flowed to save the lives of (Hagar) Hajar and Ishmael (Ismail) became a popular place for the caravans to stop. Some people liked the place so much they decided to stay there.
This place became known as Makkah. One day Ibrahim had a message from Allah. He and Ismail were to build a place for people to pray. They were to build an altar; it was to be known as the Ka'aba. The angel Gabriel (Jibrail) brought the message saying that the Ka'aba should be built near the Well of Zamzam, the most sacred place on earth. 
The foundation stone for the Ka'aba was to come from heaven. The stone is found today at a corner of the Ka'aba and is known as the black stone. When Ibrahim was building the Ka'aba he was standing on a large rock. Allah softened the rock and the foot prints of Abraham's bare feet were left in it. They are still there up to day, for all to see.

When Ibrahim was very old, the angels came to see him and said Allah that was going to give him and Sarah a son.

Sarah could not believe it was true. She was too old. The angels said that all things are possible with Allah. They said that the son was to be called Isaac (Ishaq). He was to be a prophet. Sure enough, Sarah did have a son and they called him Ishaq. He grew up to be a great prophet. Ishaq married a girl called Rebecca. They had two sons, called Esau and Jacob (Yaqub). 
Yaqub became a great prophet. Yaqub grew up and married Zia and they had lots of children, both boys and girls. His second wife Rohsie had two sons, Joseph (Yusuf) and Benjamin. Yusuf and Benjamin were very good, obedient sons and they became Yaqub's favorites because of their good behavior. Yusuf too grew up to be a prophet. All of these great prophets were descendents of Ibrahim. He is known as the father of all the prophets. 
Muhammad (s), our great and beloved prophet, the last of all the prophets was a descendant of Ismail.
