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 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt, and they die while they are disbelievers. 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 a Surah is revealed they look at each other (so as to ask): "Is anyone looking at Us?" and then turn away. Indeed God has turned their hearts away (from the truth), for they cannot discern the law of heaven. 127 Now there has come to you a Messenger from among yourselves; grievous to him is your suffering; anxious is he over you, gentle to the believers, compassionate. 128 If, then, they turn away, say thou: sufficing unto me is Allah, there is no god but he, on Him I rely and He is the Lord of Mighty Throne. 129
