I fear my husband does not pay Zakat; what should I do?

It is the wife's duty to advise her husband who does not pay zakat, because that is part of cooperating in righteousness and piety, enjoining one another to truth and patience, and because "religion is advice." Also, zakat is an obligation, and the Prophet, peace and blessings be upon him, threatened those who withhold zakat with severe punishment in the Hereafter and with the removal of blessing from their wealth in this world.
