“because they had not executed My judgments, but had despised My statutes and had polluted My Sabbaths, and their eyes were after their fathers’ idols. Therefore I gave them also statutes (Laws) that were not good and judgments whereby they should not live; and I polluted them in their own gifts, in that they caused to pass through the fire all who openeth the womb, that I might make them desolate, to the end that they might know that I am the LORD.” … Ezekiel 20:24-26
This Biblical commandment was in reference to various Laws for Israelites being made stricter and even life threatening, including dietary laws because the Israelites disobeyed God.
This is also explained in the Qur’an, Surah 6:146:
“And to those who were Jews We made unlawful every animal with undivided hoof, and of oxen and sheep We made unlawful to them the fat of both, except such as was on their backs or the entrails or what was mixed with bones: this was a punishment We gave them on account of their rebellion, and We are surely Truthful.”
And God also reveals in the following verse that camels actually are nutritional, whereas in the Torah they were forbidden not because of health reasons like pork, but because of disobedience of Israelites.
"The sacrificial camels we have made for you as among the symbols from Allah: in them is (much) good for you: then pronounce the name of Allah over them as they line up (for sacrifice): when they are down on their sides (after slaughter), eat ye thereof, and feed such as (beg not but) live in contentment, and such as beg with due humility: thus have We made animals subject to you, that ye may be grateful.” … Surah 22:36
Also, there are Jewish dietary laws which were created by Rabbis, rather than recorded in the Torah. These laws are self inflicted laws, forbidding foods on yourself that God Almighty has made lawful.
An example of this Rabbi created food restriction is the Separation of Meat and Dairy.
Because of such human made laws forbidding the bounty and blessings from God, the Qur’an was sent by the Lord and states:
“All food was lawful to the children of Israel except that which Israel had forbidden to itself, before the Torah was revealed. Say: Bring then the Torah and read it, if you are truthful.” … (3:93)
In conclusion, I would like to say that Muslims are NOT at all asking Christians to start eating camel meat, but rather, we are urging Christians to STOP eating pork for the sake of Jesus (pbuh).
