These two verses are also with reference to the inconsistent hypocrites who were hidden among the believers. They feared to take part in the battles as cowards fear. They did want to escape death, but of no use. If the secure and lofty towers could prevent a few accidental deaths, how could they prevent the natural death of man?! When due to their folly and blindness a disaster happened, they blamed the prophet and other Muslims, but if anything good befell them they said; God gave them that for their merit and superiority. The verses imply that Allah is the ultimate cause of all things, and in God's hand lays all good. On the other hand the cause of misfortune and bad luck, lay some how in our follies, wrongs, and shortcomings, and Allah will not oppress His servants the least, and as much as the husk of a date stone.
