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 chapter is revealed, there are some of them who say: Which of you has it strengthened in faith? Then as for those who believe, it strengthens them in faith and they rejoice. 124 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 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 a surah is bestowed from on high, they look at one another [and say, as it were,] "Is there anyone who can see what is in your hearts?" - and then they turn away. God has turned their hearts away [from the truth] - for they are people who will not grasp it. 127 Indeed, there has come to you a Messenger from your own, he grieves for your suffering, and is anxious about you, and is gentle, merciful to the believers. 128 Therefore, if they turn away, say: 'Allah is sufficient for me. There is no god except He. In Him I have put my trust. He is the Lord of the Mighty Throne' 129
