مُسْنَدُ أَحْمَدَ
Musnad Ahmad 2490
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Mujahid said: They mentioned him - meaning the Dajjal - and he said: Written between his eyes will be (the letters) kaf, fa’, ra'. Ibn 'Abbas (رضي الله عنه) said: I did not hear him say that; rather he said: "As for Ibraheem (عليه السلام) look at your companion - Yazeed said: meaning himself (رضي الله عنه) - And as for Moosa (عليه السلام), he was dark with curly hair, tall, 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."
