[Machine] The Messenger of Allah ﷺ mentioned the Antichrist (Dajjal) and said, "Whoever among you sees him, let him recite the opening verses of Surah Al-Kahf."  

ذَكَرَ رَسُولُ اللهِ ﷺ الدَّجَّالَ قَالَ «مَنْ رَآهُ مِنْكُمْ فَلْيَقْرَأْ فَوَاتِحَ سُورَةِ الْكَهْفِ»  

If anyone memorizes ten verses from the beginning of surat al-Kahf, he will be protected from the trial of Dajjal (Antichrist). Abu Dawud said: In this way Hashim al-dastawa’I transmitted it from Qatadah, but he said : “If anyone memorizes the closing verses of surat al-Kahf.” Shu’bah narrated from Qatadah the words “from the end of al-Kahf. (Using translation from Abū Dāʾūd 4323)   

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ قَرَأَ عَشْرَ آيَاتٍ مِنَ الْكَهْفِ عُصِمَ مِنْ فِتْنَةِ الدَّجَّالِ»
