This chapter opens with an oath. God swears by the heaven or the sky. The Arabic word used generally means everything above us, it is an infinite term. Thus He swears by everything above us, and by the night visitor. The ‘night visitor’, at-Tariq means anything that travels at night. This article titled, Surah At-Tariq (Chapter 86) (The Night Visitor), sheds light on one of the scientific miracles of the Qur’an.
