Believers! Fight against those deniers of the truth who are near you. Deal firmly with them. Know that God is with those who fear 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 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 See they not that they are tried every year once or twice? Yet they turn not in repentance, and they take no 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 A Messenger from your own people has come to you. Your destruction and suffering is extremely grievous to him. He really cares about you and is very compassionate and merciful to the believers. 128 But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power. 129
