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 chapter is sent down, some of them say, “Whose faith among you has this promoted?” So it has promoted the faith of the believers and they are rejoicing! 124 but as for those with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 125 Do they not see that they are tried once or twice in every year, yet they do not turn (to Allah) nor do they mind. 126 And whenever there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 Assuredly there hath come unto you an apostle from amongst yourselves: heavy upon him is that which harasseth you, solicitous for you, and with the believers tender and merciful. 128 Therefore, if they turn away, say: 'Allah is sufficient for me. There is no god except He. In Him I have put my trust. He is the Lord of the Mighty Throne' 129
