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 But those in whose hearts is a disease,- it will add doubt to their doubt, and they will die in a state of Unbelief. 125 Do they not see that they are tried every year once or twice? Yet still they do not repent, nor do they remember. 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 Now there has come to you a Messenger from among yourselves; grievous to him is your suffering; anxious is he over you, gentle to the believers, 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
