Narrator:Anas ibn Mālik
وعن أنس رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم :
"ما من نبي إلا وقد أنذر أمته الأعور الكذاب، ألا إنه أعور، وإن ربكم عز وجل ليس بأعور، مكتوب بين عينيه ك ف ر"
Anas ibn Mālik (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: “No Prophet was sent but that he warned his people against the one-eyed liar. Beware! He is blind in one eye, and your Lord, Glorified and Exalted, is not. Between his eyes, the letters 'k', 'f', and 'r' are written (in Arabic).”
