Islam was not the first religion to pre-ordain the Jizya and Muslims were not the first nation to levy the Jizya unto the peoples subdued by them. Victorious nations throughout history have persisted in levying the Jizya on their conquered subjects. Examples of such an action are abundant in human history.
This is reflected in the New Testament when Jesus (pbuh) told Simon the following:
“What do you think Simon? From whom do the kings of the earth collect duty and taxes – from their own sons or from others?” “From others” Peter answered. “Then the sons are exempt” Jesus said to him." (Matthew 17:24-25).
Joshua had in fact also enslaved the conquered people of Canaan when he conquered them:
“They did not dislodge the Canaanites dwelling on Gezer ; to this day the Canaanites live among the people of Ephraim but are required to pay Jizya.” (Joshua 16:10).
Thus Joshua had both enslaved and levied Jizya on the people of Canaan.
Slaves and poor were not supposed to pay Jizya when Islam introduced it.
Christianity is not supposed abrogate any of the laws of Judaism. Jesus (pbuh) did not come to abolish the Law or the Prophets, rather, he came to fulfill them (Matthew 5:17). He even commanded his followers to pay the Jizya to the Romans and he himself had expediently paid it. He told Simon:
“Go to the lake and throw your line. Take the first fish you catch; open its mouth and you will find a four-drachma coin. Take it and give it to them for my tax and yours.” (Matthew 17:24-27)
When asked by Jews about his opinion as regards the payment of the Jizya, he acknowledged Caesar’s right to take it
"They sent their disciples to him along with the Herodians. “Teacher,” they said, “we know you are a man of integrity and that you teach the way of God in accordance with the truth. You are not swayed by men, because you pay no attention to who they are. Tell us then, what is your opinion? Is it right to pay taxes to Caesar or not?” But Jesus, knowing their evil intent, said,“You hypocrites, why are you trying to trap me? Show me the coin used for paying the tax.” They brought him a denarius, and he asked them, “Whose portrait is this? And whose inscription??? “Caesar’s,” they replied. Then he said to them, “Give to Caesar what is Caesar’s, and to God what is God’s.” (Matthew 22:16-21).
The New Testament considers the payment of Jizya to the ruler as a legislative right. It is clad in holiness and is rendered as a religious matter. It says:
“Everyone must submit himself to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Consequently, he who rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and he will commend you. For he is God’s servant to do you good. But if you do wrong, be afraid, for he does not bear the sword for nothing. He Is God’s servant, an agent of wrath to bring punishment on the wrongdoer. Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also because of conscience. This is also why you pay taxes, for the authorities are God’s servants, who give their full time to governing. Give everyone what you owe him if you owe taxes, pay taxes; if revenue, then revenue; if respect, then respect; if honor, then honor.” (Romans 13:1-7).
If you don’t practice this, thats a different case.
Why do you criticize Islam then for the same thing that your Bible teaches as righteous to collect and to pay??
