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 to you, some ask: 'Which of you has it increased in belief' It will surely increase the belief of the believers and they are joyful. 124 But it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 See they not that they are tried every year once or twice? Yet they turn not in repentance, and they take no heed. 126 Whenever there cometh down a Sura, they look at each other, (saying), "Doth anyone see you?" Then they turn aside: Allah hath turned their hearts (from the light); for they are a people that understand not. 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 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
