196. " let not the (prosperous) going about of those who disbelieve
deceive you in the cities."

commentary:
because of their commercial travels, the pagans of mecca and the
jews of medina lived in welfare. but the muslims, as a result of leaving
their wealth and properties in mecca and emigrating to medina, and, on
the other hand, being involved with economical siege, were living in some
straitened circumstances. so, the revelation of this verse caused them to
console.

" let not the (rosperous) going about of those who disbelieve
deceive you in the cities."

explanations:
1. sending political, economical, and martial missions, or holding
secret meetings and having equivocal interviews performed by the enemy,
should not deceive you.
