Mujahid (may Allah have mercy on him) says: We were with Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), and the people mentioned the Dajjal and said that between his eyes will be written (K F R). Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: I did not hear this from him (peace and blessings be upon him) in this way; rather he (peace and blessings be upon him) said: "As for Sayyiduna Ibrahim (peace be upon him), look at your companion. As for Sayyiduna Musa (peace be upon him), he is a brown-complexioned man with curly hair, upon a red camel whose nose-rein is a strong rope made of palm fibre. It is as if I am looking at him as he descends from the valley, reciting the talbiyah."
