O Ye who believe! fight the infidels who are near unto you, and surely let them find in you sternness, and know that Allah is with the God-fearing, 123 Whenever a sura is sent down to thee, some of them say, 'Which of you has this increased in belief?' As for the believers, them it has increased in belief, and they are joyful. 124 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take 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 So if they turn their backs, say: 'God is enough for me. There is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne.' 129
