O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous. 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 it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 Do they not see that they are tried every year once or twice? Yet they neither repent nor take heed. 126 Whenever a chapter is sent down, they glance at each other, (asking): 'Does anyone see you' Then they turn away. Allah has turned away their hearts, for they are a nation who do not understand. 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
