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 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 But as for those in whose hearts is disease, each new message but adds another [element of] disbelief to the disbelief which they already harbour, and they die while [still] refusing to acknowledge the truth. 125 Do they not observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 And whenever a Surah is sent down they look on at each other as though saying: observeth you anyone? Thereafter they turn to go; Allah hath turned their hearts, for verily they are people who understand not. 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 (Muhammad), if they turn away from you, say, "God is Sufficient (support) for me. There is no God but He. In Him do I trust and He is the Owner of the Great Throne." 129
