Hadith 5486
Abu `Ubaida b. al-Jarrah told that he heard God's-messenger say, "There has been no prophet after Noah who has not warned his people about the dajjal, and I warn you of him." He then described him to them, saying, "Perhaps some who have seen me or heard my words will live till his time." God's messenger was asked what the condition of their hearts would be on that day, and he replied, "Like what they are (meaning at the time he was speaking), or better.' Tirmidhi and Abu Dawud transmitted it.
وَعَن أَي عُبَيْدَةَ بْنِ الْجَرَّاحِ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «إِنَّهُ لَمْ يَكُنْ نَبِيٌّ بَعْدَ نُوحٍ إِلَّا قَدْ أَنْذَرَ الدجالَ قومَه وإِني أُنذركموه» فرصفه لَنَا قَالَ: «لَعَلَّهُ سَيُدْرِكُهُ بَعْضُ مَنْ رَآنِي أَوْ سَمِعَ كَلَامِي» . قَالُوا: يَا رَسُولَ اللَّهِ فَكَيْفَ قُلُوبُنَا يَوْمَئِذٍ؟ قَالَ: «مِثْلُهَا» يَعْنِي الْيَوْمَ «أوخير» . رَوَاهُ التِّرْمِذِيّ وَأَبُو دَاوُد
