The blessed Chapter, revealed in Mecca, has 28 Verses. The designation of the Chapter reflects that it mainly treats of invisible creatures, the jinn, their belief in the Noble Prophet of the Islamic faith (S), the Holy Quran, and Resurrection, and the groups of believers and disbelievers amongst them. The closing Verses concern the knowledge of the unseen unknown to all beings besides Allah Almighty.
It is narrated from the Noble Imam Sadiq (as) as saying:
One who recites Surah al-Jinn many a time will never suffer from the evil eye, magic, and ploys of the Jinn and magicians but will accompany Muhammad (S). O Lord! I believe in none besides him and I will never turn toward anyone but him.
Reciting the blessed Chapter would be a prelude to the awareness of its contextual meaning and applying it to ones life.
