Believers, fight the unbelievers near you for the cause of God so that they realize your strength and know that God is with the pious ones. 123 And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor). 124 But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers. 125 See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they 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 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 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
