Model Behavior of the Prophet (Kitab Al-Sunnah)
Dawud :: Book 40 : Hadith 4738
Narrated AbuUbaydah ibn al-Jarrah:
I heard the Prophet (peace_be_upon_him) say: There has been no Prophet after Noah who has not warned his people about the antichrist (Dajjal), and I warn you of him. The Apostle of Allah (peace_be_upon_him) described him to us, saying: Perhaps some who have seen me and heard my words will live till his time. The people asked: Apostle of Allah! what will be the condition of our hearts on that day? Like what we are today? He replied: Or better.
