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.

9:54What prevents the acceptance of their contributions is nothing but the fact that they disbelieved in God and His Messenger, and that they do not approach the prayer except lazily, and that they do not spend except grudgingly.

9:92Nor on those who approach you, wishing to ride with you, and you said, “I have nothing to carry you on.” So they went away, with their eyes overflowing with tears, sorrowing for not finding the means to spend.
