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 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 to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 See they not that they are tried once or twice every year (with different kinds of calamities, disease, famine, etc.)? Yet, they turn not in repentance, nor do they learn a lesson (from it). 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 certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful. 128 (Muhammad), if they turn away from you, say, "God is Sufficient (support) for me. There is no God but He. In Him do I trust and He is the Owner of the Great Throne." 129
