O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear 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 those in whose hearts is a disease,- it will add doubt to their doubt, and they will die in a state of Unbelief. 125 Do they not see that they are tried every year once or twice but then they do not repent nor do they remember? 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
