وَعَن أبي الدَّرْدَاء
قَالَ ك قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ قَرَأَ ثَلَاثَ آيَاتٍ مِنْ أَوَّلِ الْكَهْفِ عُصِمَ مِنْ فِتْنَةِ الدَّجَّالِ»
Abud Darda reported God’s messenger as saying, “He who recites three verses at the beginning of al-Kahf will be protected from the trial of the dajjal.” Tirmidhi transmitted it, saying this is a hasan sahih tradition.
