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 it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 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 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 But if they turn away, say, "God suffices me: there is no deity but He: in Him I have put my trust. He is the Lord of the Glorious Throne." 129
