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 realize that God tests them once or twice a year but, nevertheless, they do not repent and give it proper thought? 126 And whenever there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 INDEED, there has come unto you [O mankind] an Apostle from among yourselves: heavily weighs - upon him [the thought] that you might suffer [in the life to come]; full of concern for you [is he, and] full of compassion and mercy towards the believers. 128 (Muhammad), if they turn away from you, say, "God is Sufficient (support) for me. There is no God but He. In Him do I trust and He is the Owner of the Great Throne." 129
