Those who responded to the call of Allah and His Noble Messenger after they had been grieved; for the virtuous and the pious among them is a great reward. 172 Men said to them: "A great army is gathering against you": And frightened them: But it (only) increased their Faith: They said: "For us Allah sufficeth, and He is the best disposer of affairs." 173 They then returned with a favour from Allah and His grace; no evil touched them! and they followed Allah's pleasure and Allah is Owner of Mighty Grace. 174 It is but Satan who instils [into you] fear of his allies: so fear them not, but fear Me, if you are [truly] believers! 175 And let not those grieve you (O Muhammad SAW) who rush with haste to disbelieve; verily, not the least harm will they do to Allah. It is Allah's Will to give them no portion in the Hereafter. For them there is a great torment. 176 Indeed, those who purchase disbelief [in exchange] for faith - never will they harm Allah at all, and for them is a painful punishment. 177 Let not those who deny the truth think that Our granting them respite is good for them: Our granting them respite will only cause them to increase in disobedience -- shameful punishment awaits them. 178 God will not leave the believers in the state they are in till He has sifted the evil from the good; nor will God reveal the secrets of the Unknown. He chooses (for this) from His apostles whom He will. So believe in God and the prophets, for if you believe and fear the displeasure of God your reward will be great. 179 Let not those who are niggardly of things that God has given them of His largesse think that this is good for them. In fact, it is worse; for what they grudged will be hung around their necks on the Day of Resurrection. To God belong the heavens and the earth, and God is aware of all you do. 180
