Azami 1575

Tirmidhi (607) narrated it from Abu Walid Ahmad bin Bakkar Dimashqi, who said, Walid bin Muslim told us, who said, Safwan bin Amr said, Yazid bin Khumayr told me, from Abdullah bin Busr, and he mentioned something similar. Tirmidhi said, "Hasan sahih gharib from this route, from the hadith of Abdullah bin Busr."Imam Ahmad (17693) and Tabarani in Musnad Shamiyin (995) narrated it more fully than this, from Abu Mughira, who said, Safwan told us, who said, Yazid bin Khumayr Rahbi told me, from Abdullah bin Busr Mazini, from the Messenger of Allah ﷺ, that he said, "There is not a single one of my nation whom I will not recognize on the Day of Resurrection." They said, "How will you recognize them, O Messenger of Allah, amid the multitude of creation?" He said, "What do you think, if you entered a herd of dark black horses among which was a horse with a white blaze and white feet, wouldn't you recognize it among them?" He said, "Yes indeed." He said, "My nation on that day will have brightness from sujud and whiteness from wudu."This chain is sahih. Abu Mughira is Abdul-Quddus bin Hajjaj Khawlani. His saying "buhmun" (with damma on the ba and sakin on the ha) means pure black.
