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 it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 Behold they not that they are tried every year once or twice? Yet they repent not, nor are they admonished. 126 And whenever a chapter is revealed, they cast glances at one another: Does any one see you? Then they turn away: Allah has turned away their hearts because they are a people who do not understand. 127 Now hath come unto you a Messenger from amongst yourselves: it grieves him that ye should perish: ardently anxious is he over you: to the Believers is he most kind and merciful. 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
