9:28O you who believe! The polytheists are polluted, so let them not approach the Sacred Mosque after this year of theirs. And if you fear poverty, God will enrich you from His grace, if He wills. God is Aware and Wise.

9:37Postponement is an increase in disbelief—by which those who disbelieve are led astray. They allow it one year, and forbid it another year, in order to conform to the number made sacred by God, thus permitting what God has forbidden. The evil of their deeds seems good to them. God does not guide the disbelieving people.

9:126Do they not see that they are tested once or twice every year? Yet they do not repent, and they do not learn.
