Believers! Fight against the unbelievers who live around you; and let them find in you sternness. Know that Allah is with the God-fearing. 123 And whenever a new surah is revealed some of the hypocrites ask the believers (in jest): "Whose faith has increased because of this?" As for those who believe, it will certainly increase their faith, and they are joyful over that. 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 Do they not observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 Whenever there cometh down a Sura, they look at each other, (saying), "Doth anyone see you?" Then they turn aside: Allah hath turned their hearts (from the light); for they are a people that understand not. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 (Muhammad), if they turn away from you, say, "God is Sufficient (support) for me. There is no God but He. In Him do I trust and He is the Owner of the Great Throne." 129
