[Taubah 9:73] O Herald of the Hidden! Fight against the disbelievers and the hypocrites, and be stern with them; and their destination hell; and what an evil place to return!
[Taubah 9:74] And they swear by Allah that they did not say it; whereas indeed they had certainly uttered the words of disbelief, and after having entered Islam turned disbelievers and had wished for what they did not get; and what annoyed them except that Allah, and His Noble Messenger, made them prosperous with His grace? So if they repent, it is better for them; and if they turn away, Allah will afflict them with a painful punishment - in this world and the Hereafter; and they will have neither a protector nor any supporter in the entire earth.
[Taubah 9:75] And among them are those who made a covenant with Allah that, "If He gives us by His munificence, we will surely give charity and surely become righteous."
[Taubah 9:76] Therefore when Allah gave them by His munificence, they hoarded it and turning their faces, went back.* (* Reneged on their promise).
[Taubah 9:77] So following this, Allah put hypocrisy in their hearts until the day when they will meet Him - the result of their breaching the promise made to Allah, and because they lied.
[Taubah 9:78] Do they not know that Allah knows their secrets and the schemes they whisper, and that Allah is the All Knowing of all the hidden?
[Taubah 9:79] Those who find fault in the Muslims who
give the charity wholeheartedly and in those who gain nothing except from
their own toil - so they mock at them; Allah will punish them for their
mocking; and for them is a painful punishment.
