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 Whenever a chapter is sent down, there are some of them who say, "Which of you has had his faith increased by it?" But, as for those who believe, it increases their faith and they rejoice, 124 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 125 Do they not see that they are tried every year once or twice? Yet they do not repent, nor would they be admonished. 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people who do not understand. 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 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
