يَكُونُ فِي آخِرِ الزَّمَانِ دَجَّالُونَ كَذَّابُونَ، يَأْتُونَكُمْ مِنَ الْأَحَادِيثِ بِمَا لَمْ تَسْمَعُوا أَنْتُمْ وَلَا آبَاؤُكُمْ، فَإِيَّاكُمْ وَإِيَّاهُمْ، لَا يُضِلُّونَكُمْ وَلَا يَفْتِنُونَكُمْ
Translation: In later times there will be deceptive liars bringing reports unfamiliar to you and your forebears. Beware of them, lest they lead you astray or plunge you into confusion.
Source: مسلم
دَجَّالُونَ كَذَّابُونَ describes deceptive liars. يَأْتُونَكُمْ means “they will bring to you,” and فَإِيَّاكُمْ وَإِيَّاهُمْ is an emphatic warning to be on guard.
The teaching concerns care with religious claims. A report is not reliable merely because it is novel, striking, or widely circulated. Statements attributed to the Prophet ﷺ deserve careful checking through trustworthy sources and knowledgeable teachers.
