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 as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers. 125 Do they not realize that God tests them once or twice a year but, nevertheless, they do not repent and give it proper thought? 126 And whenever a surah is revealed, they look at each other, [saying], "Does anyone see you?" and then they dismiss themselves. Allah has dismissed their hearts because they are a people who do not understand. 127 There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful. 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
