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 with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 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 And whenever a surah is revealed, they glance at each other as though saying: "Is anyone watching?" Then they slip away. Allah has turned away their hearts for they are a people who are bereft of understanding. 127 There has come to you a Messenger of your own. Your suffering distresses him: he is deeply concerned for your welfare and full of kindness and mercy towards the believers. 128 So if they turn their backs, say: 'God is enough for me. There is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne.' 129
