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 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 125 Are they, then, not aware that they are being tested year-in, year-out? And yet, they do not repent and do not bethink themselves [of God]; 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people 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 If, then, they turn away, say thou: sufficing unto me is Allah, there is no god but he, on Him I rely and He is the Lord of Mighty Throne. 129
