A group in the UAE called the General Authority of Islamic Affairs and Endowment have issued a fatwa barring Muslims from living on Mars.

A one-way journey like that “poses a real risk to life, and that can never be justified in Islam,” the committee said, according to the UAE-based Khaleej Times.

“Protecting life against all possible dangers and keeping it safe is an issue agreed upon by all religions and is clearly stipulated in verse 4/29 of the Holy Quran: Do not kill yourselves or one another. Indeed, Allah is to you ever Merciful,“ the committee said.
