The Time of Standing at 'Arafah and al-Mash'ar al-Haram

Question:
This man says: Explain to us the time of standing at 'Arafah and the time of departing from it.

Answer:
And where is al-Mash'ar al-Haram in Muzdalifah? The time of standing, as I explained to you, begins from the passing of the sun at its zenith on the ninth day and continues until the appearance of the dawn of the night of the tenth day. This is the time of standing. The one who stands during the day must continue until the sun sets, and it is not permissible for him to depart except after the sun has set. As for the one who stands at night, he may depart whenever he wishes. The one who stands at night may depart whenever he wishes, but the one who stands during the day is not permitted to depart until after the sun has set. It is said that al-Mash'ar al-Haram refers to the mountain in Muzdalifah on which the mosque is now located, and it is said that al-Mash'ar al-Haram refers to all of Muzdalifah, which is called al-Mash'ar al-Haram. And when a person descends in any place in Muzdalifah, he has achieved, praise be to Allah, what is required. Our Prophet (peace and blessings be upon him), when he spent the night in Muzdalifah, said: "I stood here, and all of Muzdalifah is a standing place," meaning all of Muzdalifah is a standing place, just as he said regarding 'Arafah: "I stood here, and all of 'Arafah is a standing place." So the matter is broad, praise be to Allah.
