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 And whenever a chapter is sent down, some of them say, “Whose faith among you has this promoted?” So it has promoted the faith of the believers and they are rejoicing! 124 But as for those in whose hearts is disease, each new message but adds another [element of] disbelief to the disbelief which they already harbour, and they die while [still] refusing to acknowledge the truth. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 126 and whenever a surah is bestowed from on high, they look at one another [and say, as it were,] "Is there anyone who can see what is in your hearts?" - and then they turn away. God has turned their hearts away [from the truth] - for they are people who will not grasp it. 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 So if they turn their backs, say: 'God is enough for me. There is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne.' 129
