The lonely place had turned well inhabited and a big spring of fresh water was flowing profusely where there was no drop of water when he had left his wife and son there years ago. God commanded Ibrahim (a.s) to reconstruct His House (Baitullaah) which was founded by Adam (a.s) and which was later destroyed in the flood of Noah (a.s). Accordingly, Ismail (a.s) fetched stones from Mt. Zee Tuwa to Ibrahim (a.s) who was raising the walls of the Ka’ba. The House was thus reconstructed.
Now it was the duty of Ibrahim (a.s) to call all the servants of God (every human being) to visit this House of God. In this way, this building has continued to be till today the center of worshipping only one God. Not only this, it also is one of the most ancient monuments of human civilization and culture. It is its first milestone.
Human history will forever remember how an old father had, with the assistance of his youthful son, built a House, which made Mecca an honored place in the precious land of Hijaz .[1] In the meanwhile, one night Ibrahim (a.s) saw in his dream that he was sacrificing his son in the path of God; that he had cut off the head of his son Ismail. As dreams of prophets carry revelations from God, next morning, Ibrahim (a.s) described his dream to his son Ismail (a.s).
The Merciful God has mentioned this in Quran as follows: [1] Refer verses 125-131 of Surah Baqarah So We gave him the good news of a boy, possessing forbearance. [1] When Ismail (a.s) became a major and youthful he (Ibrahim) said: O my son! Surely I have seen in a dream that I should sacrifice you; consider then what you see.
[2] Almighty God had intended to test Ibrahim and his youthful son Ismail (a.s) and to examine and measure the faith of an old father and also to see to what extent a youthful son remains steadfast on the true path so that the whole world may also know how powerful are their intentions and how solid are the faiths of the divine messengers and heavenly guides. Ismail said: O my father! Do what you are commanded; if Allah please, you will find me of the patient ones.
[3] When Ibrahim (a.s) carried out Almighty God's command and arranged for the slaughter, Ismail (a.s) said: “O my dear father! Please while slaughtering me, tie me tightly with a rope so that I may not be able to move my hands and legs at the time of slaughtering so that it may not weaken your intention. Please also cut away my clothes so that they may not redden with my blood, which my dear mother may see.
