The number of camels he took with him for sacrifice is differently stated at sixty-four, sixty-six, and a hundred according to another correct report. He entered Mecca on 4th Zilhajj. When he reached the gate of the Sacred Mosque, he entered through the gate of Bani Shaibah. Standing at the gate of the Mosque he praised and glorified the Almighty and invoked blessings of his noble ancestor, Ibrahim (a.s.).
Then he came to the Black Stone, drew his hand over it and kissed it and he went around the holy Kaaba seven times. He prayed two units of Tawaf prayer behind the Place of Ibrahim. Then he went to the Zamzam well and tasted the water and said: O Lord, verily, I have asked of thee that wisdom which profits and that healing which is sufficient for all ills.
He then descended from this hill and ascended mount Marwah, where he continued as long as he had done on Safa. After this, he went again to the latter mountain and prayed and returned to Marwah, and thus continued to pass from one to the other till he had visited each seven times ( Sayy ). When this task was performed, and was yet standing on Marwah, he turned to the people and recited praise and thanksgiving to Allah.
He then made a sign behind himself and said, “This is Jibraeel, and he commands me to order all who have not brought sacrifices with them, to withdraw by themselves and change their Hajj to an Umrah, which if I had known before, I would not have brought a sacrifice myself. But I have brought sacrifices and I cannot back out from Hajj.
