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 sura is sent down to thee, some of them say, 'Which of you has this increased in belief?' As for the believers, them it has increased in belief, and they are joyful. 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 a chapter is sent down, they glance at each other, (asking): 'Does anyone see you' Then they turn away. Allah has turned away their hearts, for they are a nation who do not understand. 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 But if they turn away, [O Muhammad], say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne." 129
