وَعَنْ أَبِي سَعِيدٍ رَضِيَ اللَّهُ عَنْهُ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «من قَرَأَ سُورَة الْكَهْف فِي يَوْم الْجُمُعَة أَضَاء لَهُ النُّور مَا بَيْنَ الْجُمْعَتَيْنِ»
The Prophet (sallallahu alayhi wa sallam) said:, “If anyone recites sura al-Kahf (Qur’an, 18) on Friday, light will shine brightly for him till the next Friday.” Baihaqi transmitted it in al-Daawat al-kabir.
