The Prophet ﷺ said: The Last Hour will not come before there come forth thirty liar Dajjals (fraudulents) lying on Allah and His Apostle. (Using translation from Abū Dāʾūd 4334)
قَالَ رَسُولُ اللهِ ﷺ لَا تَقُومُ السَّاعَةُ حَتَّى يَخْرُجَ ثَلَاثُونَ كَذَّابًا دجَالًا كُلُّهُمْ يَكْذِبُ عَلَى اللهِ وَرَسُولِهِ
