عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((سَيَكُونُ فِي أُمَّتِي دَجَّالُونَ كَذَّابُونَ يُحَدِّثُونَكُمْ بِبِدَعٍ مِنَ الْحَدِيثِ بِمَا لَمْ تَسْمَعُوهُ أَنْتُمْ وَلَا آبَاؤُكُمْ، فَإِيَّاكُمْ وَإِيَّاهُمْ! لَا يَفْتِنُونَكُمْ))
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Soon there will arise in my Ummah Dajjal and liars, they will narrate to you new ahadith which neither you nor your forefathers have heard, so beware of them, lest they lead you into tribulation."
