“Halal is not a choice for Muslims, its mandatory” Halal means what is lawful or permitted. Halal is not a choice for Muslims but a requirement. In Islam, eating is considered to be a matter of worship of Allah like prayer, fasting, alms-giving and other religious activities.
It is mentioned in a Hadith that the Dua (supplication) of a person is rejected by Allah if his food is Haram.
Hadith states that Jahannam (hell-fire) is more deserving of the flesh which has been nourished with Haram. The basic principle is that all things created by Allah are permitted, with a few exceptions that are specifically prohibited. To make something lawful and unlawful is the right of Allah the al-mighty alone. Prohibiting what is permitted by Allah and permitting what is prohibited by Allah is similar to ascribing partners with Allah. The reasons for the prohibition are due to impurity and harmfulness. Good intentions do not make the unlawful acceptable.
