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 there cometh down a sura, some of them say: "Which of you has had His faith increased by it?" Yea, those who believe,- their faith is increased and they do rejoice. 124 But as for those in whose hearts is disease, it has [only] increased them in evil [in addition] to their evil. And they will have died while they are 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 And whenever a sura is sent down, they look one at another: 'Does anyone see you?' Then they turn away. God has turned away their hearts, for that they are a people who do not understand. 127 There has come to you a Messenger of Allah from among yourselves, who is distressed by the losses you sustain, who is ardently desirous of your welfare and is tender and merciful to those that believe. 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
