O you who have attained to faith! Fight against those deniers of the truth who are near you, and let them find you adamant; and know that God is with those who are conscious of 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 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 Whenever a Surah is revealed they look at each other (so as to ask): "Is anyone looking at Us?" and then turn away. Indeed God has turned their hearts away (from the truth), for they cannot discern the law of heaven. 127 Certainly an Apostle has come to you from among yourselves; grievous to him is your falling into distress, excessively solicitous respecting you; to the believers (he is) compassionate, 128 But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power. 129
