إِنَّ رَبَّكَ لَبِالْمِرْصَادِ (Surely your Lord is ever on the watch....89:14]. The
word mirsad or marsad [ is derived from the root rasada which means 'to lie in wait or on watch']. Thus it means 'an ambush, or a place of observation; it is usually used for a place where persons have to travel through a pass in which someone is lying in wait to strike them'. The verse purports to say that Allah is ever watching and observing their movements and activities. No one should think that he could escape Divine torment, because all are under His authority and Power, and He may administer His punishment whenever He wills. Some commentators state that this verse is the subject of the five oaths mentioned taken in the first five verses of this Surah.
