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 Whenever a chapter is sent down to you, some ask: 'Which of you has it increased in belief' It will surely increase the belief of the believers and they are joyful. 124 But as for those in whose heart is sickness, them it has increased in abomination added to their abomination, and they have died while they were 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 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 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 So, if they turn away, say to them: "God is sufficient for me. There is no God but He; I depend on Him alone, the Lord of the glorious Throne." 129
