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 Whenever a chapter is sent down, there are some of them who say, "Which of you has had his faith increased by it?" But, as for those who believe, it increases their faith and they rejoice, 124 But it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they heed. 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 So, if they turn away, say to them: "God is sufficient for me. There is no God but He; I depend on Him alone, the Lord of the glorious Throne." 129
