Trials and Fierce Battles (Kitab Al-Fitan Wa Al-Malahim)

Dawud :: Book 35 : Hadith 4231

Narrated Hudhayfah ibn al-Yaman:

I swear by Allah, I do not know whether my companions have forgotten or have pretended to forgot. I swear by Allah that the Apostle of Allah (peace_be_upon_him) did not omit a leader of a wrong belief (fitnah)--up to the end of the world--whose followers reach the number of three hundred and upwards but he mentioned to us his name, his father's name and the name of his tribe.
