Silsilat al-Ahadith al-Sahihah

Imam Mujahid says: We were sitting with Sayyiduna Abdullah bin Abbas (may Allah be pleased with them). People began to discuss the Dajjal. A man said: The word "Kafir" will be written on his forehead. Sayyiduna Ibn Abbas (may Allah be pleased with them) said: I have not heard this from the Prophet (peace and blessings be upon him), but I did hear that the Prophet (peace and blessings be upon him) said: "(If you) want to estimate the appearance of Ibrahim (peace be upon him), then look at your companion (i.e., me, Muhammad, peace and blessings be upon him), and Musa (peace be upon him) was wheat-colored, his hair was curly, and in the vision shown to me, he was riding a red camel, which had a bridle made of the rope of a date-palm tree, and he was descending into the valley while reciting the Talbiyah."
