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 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 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 And whenever there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 There has come to you a Messenger of your own. Your suffering distresses him: he is deeply concerned for your welfare and full of kindness and mercy towards the believers. 128 Therefore, if they turn away, say: 'Allah is sufficient for me. There is no god except He. In Him I have put my trust. He is the Lord of the Mighty Throne' 129
