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 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 But it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 Do they not realize that God tests them once or twice a year but, nevertheless, they do not repent and give it proper thought? 126 Whenever a Surah is revealed they look at each other (so as to ask): "Is anyone looking at Us?" and then turn away. Indeed God has turned their hearts away (from the truth), for they cannot discern the law of heaven. 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 But if they turn away, [O Muhammad], say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne." 129
