Is it obligatory for the pilgrim to stand at 'Arafah until the sun sets?

The questioner : May Allah reward you with good. He says:The questioner : Is it a condition for the pilgrim to combine the night and the day in his standing at 'Arafah? And if that is a condition, what is the explanation regarding the hadith of 'Urwah, who came to the Messenger of Allah (peace and blessings be upon him) and had stood at 'Arafah during the night or the day?

The Shaykh : Yes, it is obligatory for one who stands during the day to remain until the night; this is the obligation. As for one who stands only at night, that suffices for him, even if he does not stand during the day. As for the hadith of 'Urwah ibn al-Muth'ir (may Allah be pleased with him), it is a general hadith, as you know, because he said, "I did not leave a mountain without standing on it," or he said, "at it." Then the Prophet (peace and blessings be upon him) said: meaning the Fajr prayer at Muzdalifah . It is known that this hadith is not to be taken in its absolute sense, because there are other things that are necessary for the completion of Hajj, such as tawaf and sa'y. However, his intention is that one who stands at night or during the day has completed his Hajj, considering the standing alone. As for the evidence for the obligation of remaining until the night for one who stood during the day, it is the action of the Messenger (peace and blessings be upon him). The Prophet (peace and blessings be upon him) stood until the sun set and the yellowish light disappeared slightly, until the disk was hidden, and then he proceeded. It is known that proceeding before this time, i.e., during the day, is easier for people. So the deviation of the Messenger (peace and blessings be upon him) from the easier to the more difficult indicates that there is no dispensation in it. Furthermore, proceeding at the end of the day, when the sun sets, resembles the disbelievers in their Hajj. The disbelievers in their Hajj would proceed from 'Arafah when the sun was over the heads of the mountains, like the turbans of men, meaning at sunset they would proceed. So the Prophet (peace and blessings be upon him and his family) differed from them and remained until the sun set. What we see is that the correct opinion is that it is necessary for one who stands during the day to remain until the sun sets. And I have understood the way of explaining the hadith of 'Urwah.
