Sayyiduna ‘Urwah bin Mudarris (may Allah be pleased with him) narrates: I came to the service of the Prophet (peace and blessings be upon him) while he was encamped at Muzdalifah. I said,“O Messenger of Allah! I have come to you from the two mountains of Tai’, I have exhausted my mount and myself. By Allah! I did not leave any mountain but that I stayed there. Will my Hajj be valid, O Messenger of Allah?”The Prophet (peace and blessings be upon him) said:“Whoever offered the morning prayer with us at Muzdalifah and reached ‘Arafat by night or day before that, he has fulfilled his vow and his Hajj is complete.”

Sayyiduna ‘Urwah bin Mudarris (may Allah be pleased with him) narrates: I came to the service of the Noble Prophet (peace and blessings be upon him) while you were at Muzdalifah. I said,“O Messenger of Allah! Has my Hajj been accomplished?”The Noble Prophet (peace and blessings be upon him) said:“Whoever performs this prayer with us and stays with us until we depart, or whoever departs from ‘Arafat at night or during the day before this, his Hajj is complete and he has fulfilled his vow.”Imam Shafi‘i (may Allah have mercy on him) states: Whoever is unable to stay at Muzdalifah should consider it as ‘Umrah.

Sayyiduna Abdur Rahman bin Ya'mar Daili (may Allah be pleased with him) narrates: I came to the service of the Noble Prophet (peace and blessings be upon him) while he was encamped at Arafah. Some people from Jeddah came to him and said, "O Messenger of Allah! What is Hajj?" The Noble Prophet (peace and blessings be upon him) said: "Hajj is (standing at) Arafah. Whoever reaches Arafah before dawn on the Day of Sacrifice, his Hajj is complete. The days at Mina are three, but whoever departs after two days, there is no sin upon him, and whoever stays later (i.e., on the third day), there is also no sin upon him."

This narration is also transmitted with another chain of transmission.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever stands at Arafat during the night has attained Hajj, and whoever was not able to stand at Arafat during the night, his Hajj will be considered missed, so he should enter into the state of Ihram for Umrah, and now Hajj will be obligatory upon him the following year." The narrator named Rahmat bin Mus'ab is weak, and no one else has narrated this narration except him.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said:“Whoever reaches Arafat and stands there, and also reaches Muzdalifah, his Hajj is complete. And whoever does not reach Arafat, his Hajj will not be complete; he should assume Ihram for Umrah, and now Hajj will be obligatory upon him the following year.”
