Umar asked...
Umar asked, “How is it possible for us to quit Hajj when the water of Ghusl Janabat is dripping from our heads?” The Prophet answered, “You will never believe in Hajj Tamatto.” Sarafa bin Malik bin Jathan Kalani arose and said, “O Messenger of Allah, we understand the rules of our religion but as if we had been this day created; tell us, then if what you have ordered is peculiar to this year, or pertains to every Hajj?” The Prophet replied, “This order is forever.
He then closed his hands by intersecting his fingers together, and said, “The Umrah has entered the Hajj, to be united with it till the Judgment Day.” At this juncture, Amirul Momineen (a.s.) returned from Yemen as the Prophet had called him in Mecca, and going directly to his house found his wife, Fatima had completed the Hajj and dressed in colored garments was smelling of perfume.
In astonishment he inquired the cause of this premature joy, to which she replied that the Prophet had so commanded. Imam Ali (a.s.) came to the Prophet to know the facts. He said: O Messenger of Allah (S), I saw Fatima free from restrictions of Hajj. The Prophet said: I have thus commanded the people. On what have you tied up the Ihram? He replied: Like you. The Holy Prophet (S) said: Remain with Ihram, like me and share in the animals of sacrifice.
Imam Sadiq (a.s.) says: The Prophet and his companions in coming to Mecca encamped at Abtah (and not in anyone’s house) near noon on the eighth of the month Zilhajj.
till he reached Mina, where the prayers for noon, evening, night, sleep and dawn, were performed. On the morning of the ninth day, the Prophet and his companions advanced to Mount Arafat. One of the many innovations of Quraish was that they refused to advance further than Mashar-ul-Haram, saying they belonged to the sacred place and would not leave it. The rest of the people advanced to Arafat, and on their return to Mashar, the Quraish joined them and proceeded with them back to Mina.
