Re: interpreting these verses
People on kufars side had testified that they saw big horseman charging over them and putting and muslims also saw them fighting from their side. Actually the verses were revealed after the fight i think and it was told to muslims that they need not think themselves alone in fight as Allah is with them. (Allah knows best, may be someone can tell some better interpretation or may be my facts are wrong). In fact i had read somewhere that the Kuffars got so terrorized that either they scummbed to muslim warriors (70 died approx) or they left the battle field.
second one i am not sure what were the circumstances. On the face it is a message not to be fearful in war.
so what you are telling is, it is just a part of history. should this to be implemented in any other war that happens now?
