9:58And among them are those who criticize you in regard to charities. If they are given some of it, they become pleased; but if they are not given any, they grow resentful.

9:74They swear by God that they said nothing; but they did utter the word of blasphemy, and they renounced faith after their submission. And they plotted what they could not attain. They were resentful only because God and His Messenger have enriched them out of His grace. If they repent, it would be best for them; but if they turn away, God will afflict them with a painful punishment—in this life and in the Hereafter—and they will have on earth no protector and no savior.
