AskAMufti.com gives a ruling about using zabihah.com. To be clear, the only criterion for being listed on our site is that food with zabihah halal meat (Islamically slaughtered) are available for sale at the establishment. We realize there are differences of opinion as to hand vs. machine slaughtered meat, presence of alcohol and non-halal meat, etc. so we try to convey this information as it is presented to us so that you can decide for yourself whether you feel comfortable eating there. The more information you share with us, the more we can communicate to our readers!
