*121) From the apparent wording of this verse, it may be inferred that only those Muslims have at first been held responsible to fight with those enemies of Islam who live near their territory. But if we read this verse along with the succeeding passage, it becomes clear that here "disblievers who are near you refers to those hypocrites who were doing great harm to to Islamic Society by mixing up with the sincere Muslims. This very thing was stated in v. 73 at the beginning of this discourse. The Command has been repeated at its end in order to impress on the Muslims the importance of the matter and to urge them to do Jihad and crush these internal enemies, without paying the Least regard to the racial, family and social relations that had been proving a binding force with them. The only difference between the two Commands is that in v. 73, the Muslims were asked to do Jihad with them, while in this verse stronger words, "fight with them" , have been used, which were meant to impress on them that they should crush the hypocrites thoroughly and completely. Another difference in the wordings is that in v. 73, two different words, "disbelievers and hypocrites", have been used, while in this verse only one word, "disbelievers", has been used so that the hypocrites should forfeit all their claims as Muslims, for there was room for this concession in the word "hypocrite"
*122) This is meant to impress that they should not, in future, show the lenient treatment they had been meting out to them up to that time. This has already been commanded in v. 73: "be firm and stern with them".
*123) This warning has two-fold meanings and both are implied here. First, "If you show any kind of leniency towards them because of your personal or family or economic connections with them, you should know that such a thing shall be against the fear of God', for the fear of God and friendly relations with the enemies of Allah are contradictory things. Therefore, you should give these up, if you desire to obtain Allah's help". Secondly, "You should scrupulously observe the moral and humane limits in doing Jihad, and in fighting with them. For you should always keep yourselves within the prescribed limits in everything. If you transgress these in any way, you should know that Allah will forsake you for He helps only those who are Godfearing.
