Sheikh Zoubir Bouchikhi, Imam of the Islamic Society of Greater Houston’s Southeast Mosque, states the following: “Working in a place that sells foods containing that contains pig meat is haram, as it is exactly like delivering wine and beer.
Through making analogical deduction (Qiyas), eating pork is prohibited for a Muslim, based upon the ruling governing alcohol. Therefore, selling pork is like selling alcohol, in terms of being haram. The same applies to all the other 10 categories of people dealing with alcohol, whom the Prophet (peace and blessings be upon him) has cursed (in a well-known hadith).
So, whoever delivers pork is doing something haram, exactly like the person who distributes alcohol, even if he does not drink it.”
Also, Dr. Abdus-Sattaar Fathallah As-Sa`eed, professor of Qur’anic sciences at Al-Azhar University, adds:
“Working in such a place is not the normal choice or career for a Muslim. You are allowed to work there only if you find it extremely difficult to find a lawful way of earning a living. Try to keep in mind that you should leave this job the moment you find a more suitable one. If you are driven by the sincere intention to find a lawful way of earning a living, Allah Almighty will make it easy for you, Inshaa’Allah.”
