Sayyiduna ‘Urwah bin Mudarris (may Allah be pleased with him) reports: I came to the Prophet (peace and blessings be upon him) at Muzdalifah. I said: I have come to you from the mountains of Tayy; I have exhausted my mount and stood on every mountain (of the way). (Is my Hajj valid?) He replied: Whoever has performed this prayer (Maghrib and ‘Isha) with us and has stood at ‘Arafah by night or day, he has removed his impurity and his Hajj is complete.
