O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous. 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 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 See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they 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 Now, if they turn away (O Muhammad) say: Allah sufficeth me. There is no Allah save Him. In Him have I put my trust, and He is Lord of the Tremendous Throne. 129
