Believers! Fight against the unbelievers who live around you; and let them find in you sternness. Know that Allah is with the God-fearing. 123 And whenever a chapter is sent down, some of them say, “Whose faith among you has this promoted?” So it has promoted the faith of the believers and they are rejoicing! 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 see that they are tried every year once or twice? Yet they do not repent, nor would they be admonished. 126 And whenever a Surah is sent down they look on at each other as though saying: observeth you anyone? Thereafter they turn to go; Allah hath turned their hearts, for verily they are people who understand not. 127 Indeed there has come to you a Noble Messenger from among you – your falling into hardship aggrieves him, most concerned for your well being, for the Muslims most compassionate, most merciful. 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
