The Messenger of Allah ﷺ said, "Allah takes pride before the angels in the people standing at Arafat, saying, 'Look at My servants, dishevelled and dust-covered.'"
قال رسول الله ﷺ: إن الله عز وجل يباهي الملائكة بأهل عرفات، يقول: انظروا إلى عبادي شعثا غبرا.
Ahmad (8047) narrated it from Abu Qatan and Ismail bin Umar, who both said, Yunus told us, from Mujahid Abu Hajjaj, from Abu Hurairah, and he related the hadith. Its chain is hasan because of Yunus, who is Ibn Abu Ishaq, for his hadith is hasan.
