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 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 125 Do they not see how once or twice every year they are tried? Yet still they neither repent nor remember. 126 When a chapter (of the Quran) is revealed, (it upsets them). They look at one another and their eyes silently ask this question, "Has any one noticed the disappointment on our faces?" Then they walk away. In fact, God has turned their hearts away (from the truth); they are a people who have no understanding. 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
