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 sura is sent down to thee, some of them say, 'Which of you has this increased in belief?' As for the believers, them it has increased in belief, and they are joyful. 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 observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 Whenever a chapter is revealed, they glance at each other, asking, "Is anyone watching?" Then they turn away. God has turned their hearts away, because they are people who do not understand. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 But if they turn away, Say: "Allah sufficeth me: there is no god but He: On Him is my trust,- He the Lord of the Throne (of Glory) Supreme!" 129
