Opposing the polytheists is a religious requirement, which the Prophet ﷺused to emphasize and encourage. All the Companions (may Allah be pleased with them) followed his guidance concerning that. In this hadeeth, the Taabi'ee, 'Amr ibn Maymoon, reports that he witnessed 'Umar ibn al-Khattaab (may Allah be pleased with him) while he was in Hajj offering the Fajr prayer at al-Muzdalifah. Al-Muzdalifah is the name for a place where the pilgrims encamp for the night after departing from 'Arafaat and spend the night of the tenth of Thoo al-Hijjah there. The site contains the al-Mash'ar al-Haraam, and it is about 12 km away from 'Arafah and is next to the monument of Minaa. Al-Muzdalifah is also known as Jam' (combining) because two prayers, Maghrib and 'Ishaa, are combined therein. It is said that it has been given that name due to the action of its [temporary] residents because they congregate therein and they "Yazdalifoon" (get closer) to their Lord; meaning, they draw closer to Him by remaining therein [for His sake]. It was also said that the reason to name it as thus was something else. Then, 'Umar ibn al-Khattaab (may Allah be pleased with him) clarified to the people that the polytheists did not use to march out of al-Muzalifah to Minaa until the sunrise and they would utter, "Brighten up, Thabeer!" Thabeer is a mountain in al-Muzdalifah toward the left of the path going to Minaa and towards the right path going to 'Arafaat. The meaning of this utterance: Let the sun rise upon you, O Thabeer! So that we can pour out from Muzdalifah to Minaa. Thus, the Prophet ﷺopposed them concerning this practice and he departed from 'Arafaat when the morning had tuned golden and the daylight had appeared, however, before the sunrise. This hadeeth denotes the time to move out of Muzdalifah and march on to Minaa which is during the golden hour of the morning [before the sunrise]..
