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 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 But those in whose hearts is a disease,- it will add doubt to their doubt, and they will die in a state of Unbelief. 125 Do they not see that they are tried every year once or twice? Yet they neither repent nor take heed. 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people who do not understand. 127 Indeed, there has come to you a Messenger from your own, he grieves for your suffering, and is anxious about you, and is gentle, merciful to the believers. 128 Now, if they turn away (O Muhammad) say: Allah sufficeth me. There is no Allah save Him. In Him have I put my trust, and He is Lord of the Tremendous Throne. 129
