It is narrated from Hazrat Marrah that once we were with the Prophet (peace be upon him) on a road in Madinah Munawwarah. The Prophet (peace be upon him) said, "What will you do when tribulations spread throughout the world like the horns of a cow?" The people asked, "O Messenger of Allah, what should we do at that time?" Meanwhile, a veiled man passed by. The Prophet (peace be upon him) saw him and said, "He and his companions will be upon the truth at that time." I followed him, caught hold of his shoulder, turned his face towards the Prophet (peace be upon him), and asked, "This man?" The Prophet (peace be upon him) said, "Yes." When I looked, it was Hazrat Uthman Ghani.
