مُسْنَدُ أَحْمَدَ
Musnad Ahmad 2489
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Mujahid said: We were with Ibn 'Abbas (رضي الله عنه) and they mentioned the Dajjal, saying that written between his eyes will be (the letters) kaf, fa', ra'. He said: What are you saying? He said: They are saying that written between his eyes will be (the letters) kaf, fa', ra'. Ibn 'Abbas (رضي الله عنه) said: I did not hear him say this; rather he said: "As for Ibraheem (عليه السلام), look at your companion (meaning himself). As for Moosa (عليه السلام), he was dark with curly hair, riding a red camel with reins of palm-fibres. It is as if I can see him going down into the valley, reciting the Talbiyah.”
