Hadith text
Narrated Mujahid:That when the people mentioned before Ibn `Abbas that the Dajjal would have the word Kafir, (i.e. unbeliever) or the letters Kafir (the root of the Arabic verb 'disbelieve') written on his forehead, I heard Ibn `Abbas saying, "I did not hear this, but the Prophet (ﷺ) said, 'If you want to see Abraham, then look at your companion (i.e. the Prophet) but Moses was a curly-haired, brown man (who used to ride) a red camel, the reins of which was made of fibres of date-palms. As if I were now looking down a valley
Mujahid bataate hain: Jab logon ne Ibn Abbas ke saamne zikar kiya ke Dajjal ke mathe par \"Kafir\" (yaani avishwasi) lafz likha hoga, maine Ibn Abbas ko kehte suna, "Maine yeh nahi suna, magar Nabi ne kaha, 'Agar tum Ibrahim ko dekhna chahte ho, apne sathi (yaani Nabi) ko dekho, magar Musa ek ghungrale baal wale, bhure rang wale shaks the (jo sawari karte the) ek laal unt par jiski lagaam khajoor ke reson se bani thi. Mano abhi bhi main ek waadi ki taraf neeche dekh raha hoon (unhe dekhte huye).'"
