O believers, fight the unbelievers around you, and let them realise that you are firm: Remember, God is with those who are pious and obedient to Him. 123 Whenever a chapter is sent down, there are some of them who say, "Which of you has had his faith increased by it?" But, as for those who believe, it increases their faith and they rejoice, 124 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 125 Do they not see that they are tried once or twice in every year, yet they do not turn (to Allah) nor do they mind. 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 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 But if those [who are bent on denying the truth] turn away, say: "God is enough for me! There is no deity save Him. In Him have I placed my trust, for He is the Sustainer, in awesome almightiness enthroned." 129
