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 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 as for those in whose hearts is disease, each new message but adds another [element of] disbelief to the disbelief which they already harbour, and they die while [still] refusing to acknowledge the truth. 125 Do they not see that they are tried every year once or twice? Yet they neither repent nor take heed. 126 Whenever there cometh down a Sura, they look at each other, (saying), "Doth anyone see you?" Then they turn aside: Allah hath turned their hearts (from the light); for they are a people that understand not. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 But if those [who are bent on denying the truth] turn away, say: "God is enough for me! There is no deity save Him. In Him have I placed my trust, for He is the Sustainer, in awesome almightiness enthroned." 129
