What is the ruling on staying overnight at Muzdalifah, and when does its time begin and end?

Question : Honorable Shaykh, what is the ruling on staying overnight at Muzdalifah, and when does its time begin and end?

Answer : In the name of Allah, the Most Gracious, the Most Merciful. Praise be to Allah, Lord of the worlds. May Allah send prayers and blessings upon our Prophet Muhammad, his family, his Companions, and those who follow them in excellence until the Day of Judgment.
Staying overnight at Muzdalifah is obligatory; this is the correct opinion among the scholars' views. It is among the spoils of the one who says it is a pillar without which Hajj is not completed.
So its time begins after standing at 'Arafah. By the saying of Allah, Blessed and Exalted is He: . Yes. Because the Prophet (peace and blessings be upon him) only stood at Muzdalifah after he had stood at 'Arafah. When he reached Muzdalifah after departing from 'Arafah, he prayed there, combining and shortening Maghrib and 'Isha' from the time he arrived until he lay down until the dawn appeared.
There is no tahajjud in this night. Because the Prophet (peace and blessings be upon him) did not do it. But there is witr in it, because the Prophet (peace and blessings be upon him and his family) did not leave witr, whether resident or traveling. Yes.

The weak and the women may depart from Muzdalifah in the last part of the night. Because the Prophet (peace and blessings be upon him and his family) permitted them to depart from Muzdalifah in the last part of the night. And Asma' bint Abi Bakr (may Allah be pleased with them both) used to depart when the moon set. It does not set on the tenth night except after two-thirds of the night have passed.
Likewise, the one who is accompanying these weak people and women may follow them in the last part of the night.
When a person departs from Muzdalifah, whether to wait for light or in the time permitted by dispensation, he begins by stoning the Jamrat al-Aqabah upon reaching Mina, before anything else. So if he stones it before the dawn, there is no blame on him.
The Prophet (peace and blessings be upon him and his family) only permitted those he permitted from the women and the weak so that they may stone before the presence of the people. And it is not required to wait until the sun rises. If we obligated them to wait until the sun rises, there would be no benefit in their departure in the last part of the night. It is narrated from the Prophet (peace and blessings be upon him) that he So in its authenticity, that
