A- (The Light) النُورُ
A person, who wants his heart to be illuminated, should say the above mentioned attribute of Allah repeatedly. (Surah 24)
B-(The Cave) الْكَهْفِ(Surah No. 18)
One who recites the whole Surah Al-Kahf once every Friday, his heart will remain illuminated till the following Friday. And if a person recites the first ten verses of this Surah everyday, he will be safeguarded and protected from the temptations and trials of Dajjal.
