Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) mounted a horse and spurred it on, and his thigh became uncovered. The people of Najran saw a black mole on his thigh and said: "This is the one whom we find mentioned in our Book, that he will expel us from our land."
Tabarani recorded it, and its chain is hasan (good).
