It was narrated from Usmah bin Zaid that when the Prophet departed from Arafat he turned toward the mountain pass. I said to him:

"Are you going to pray Magrib?" He said: "The prayer place is still ahead of you."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، عَنْ كُرَيْبٍ، عَنْ أُسَامَةَ بْنِ زَيْدٍ، أَنَّ النَّبِيَّ ﷺ حَيْثُ أَفَاضَ مِنْ عَرَفَةَ مَالَ إِلَى الشِّعْبِ قَالَ فَقُلْتُ لَهُ أَتُصَلِّي الْمَغْرِبَ قَالَ " الْمُصَلَّى أَمَامَكَ " .
