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 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 how once or twice every year they are tried? Yet still they neither repent nor remember. 126 Whenever a chapter is sent down, they glance at each other, (asking): 'Does anyone see you' Then they turn away. Allah has turned away their hearts, for they are a nation who do not understand. 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 But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power. 129
