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 there cometh down a sura, some of them say: "Which of you has had His faith increased by it?" Yea, those who believe,- their faith is increased and they do rejoice. 124 But those whose hearts are affected with the disease (of hypocrisy), every new surah added a fresh abomination to their abomination. They remained unbelievers till their death. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 126 And whenever a sura is sent down, they look one at another: 'Does anyone see you?' Then they turn away. God has turned away their hearts, for that they are a people who do not understand. 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
