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 revealed, there are some of them who say: Which of you has it strengthened in faith? Then as for those who believe, it strengthens them in faith and they rejoice. 124 And as for those in whose hearts is a disease, unto them it hath increased pollution to their pollution, and they die while they are infidels. 125 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 126 And whenever there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 Assuredly there hath come unto you an apostle from amongst yourselves: heavy upon him is that which harasseth you, solicitous for you, and with the believers tender and merciful. 128 But if they turn away, say (O Muhammad SAW): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He), in Him I put my trust and He is the Lord of the Mighty Throne. 129
