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 Surah is sent down, there are some of them who say which of you hath this increased in faith! As for those who believe, it hath increased them in 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 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 To you has come an Apostle from among you. Any sorrow that befalls you weighs upon him; He is eager for your happiness, full of concern for the faithful, compassionate and kind. 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
