Believers, fight the unbelievers near you for the cause of God so that they realize your strength and know that God is with the pious ones. 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 as for those with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 125 Behold they not that they are tried every year once or twice? Yet they repent not, nor are they admonished. 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 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 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
