Answer:
Hazrat Ibrahim had a blessed family because he was a prophet. Most importantly, the reason in this that he had alot sacrifices for Allah and Islam. When the little amount of dates and water left by Ibrahim was over within few days, she felt thirsty and her infant son Ismail was crying to death. She ran madly between the two nearby hillocks of Safa and Marwah looking for water. She ran seven times. The hills and hillocks echoed with her cries. This was an ordeal, a great ordeal of God. She cried again and again but called none except Him. God showered His mercy upon her and a forceful spring of sweet water gushed out near Ismail’s feet. She called it Zamzam and it is flowing at the same place for the last 4,000 years. Almighty Allah declared Safa and Marwah as His signs and ordained the pilgrims to run seven times between them like His devoted lady, Hajrah: “Behold! Safa and Marwa are among the Symbols of Allah. So if those who visit the House in the Season or at other times, should compass them round, it is no sin in them. And if any one obeyeth his own impulse to Good, be sure that Allah is He Who recogniseth and knoweth.
