O you who have attained to faith! Fight against those deniers of the truth who are near you, and let them find you adamant; and know that God is with those who are conscious of Him. 123 And whenever a Surah is sent down, there are some of them who say which of you hath this increased in faith! As for those who believe, it hath increased them in faith, and they rejoice. 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take 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 Now hath come unto you a Messenger from amongst yourselves: it grieves him that ye should perish: ardently anxious is he over you: to the Believers is he most kind and merciful. 128 Yet, if they should turn away, then tell them: "Allah is sufficient for me; there is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne." 129
