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 sura is sent down to thee, some of them say, 'Which of you has this increased in belief?' As for the believers, them it has increased in belief, and they are joyful. 124 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 125 Do they not see how once or twice every year they are tried? Yet still they neither repent nor remember. 126 And whenever a surah is revealed, they look one at another (as who should say): Doth anybody see you? Then they turn away. Allah turneth away their hearts because they are a folk who understand not. 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 Yet, if they should turn away, then tell them: "Allah is sufficient for me; there is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne." 129
