“A man will come to you who looks with the two eyes of a devil. When he comes to you, do not speak to him." Then a man with bleary eyes came in and the Messenger of Allah (ﷺ) spoke to him and said: "Why are you and So and so," a number of people whom he named, “reviling me?” The man went and called them, and they swore by Allah and gave their excuses. Then Allah, may He be glorified and exalted, revealed the words: "and they swear to a lie while they know..." [al-Mujadilah 58:18].
