O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him. 123 And whenever a chapter is revealed, there are some of them who say: Which of you has it strengthened in faith? Then as for those who believe, it strengthens them in 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 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 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 Assuredly there hath come unto you an apostle from amongst yourselves: heavy upon him is that which harasseth you, solicitous for you, and with the believers tender and merciful. 128 If, then, they turn away, say thou: sufficing unto me is Allah, there is no god but he, on Him I rely and He is the Lord of Mighty Throne. 129
