Assalamualykun I hipe this message reaches you in good health in sha Allha. I wanted to know if supermarket or a resturant say its meat is halal, should we take there word for it and eat the meat? Or do we have to make sure its halal by finding our ourself? I ask this because in the UK this is quite a big problem because some butchers stun and electric shock the animal before it gets slaughterd. And some kill the animals with a machine therefore, we dont know how the animal was really killed. When the prophet saw told us to stay away from doubtful things because it could be haram and also when he saw said we should not nourish ourself with haram otherwise our duas will not be excepted. Does this apply to my question? Jazak Allah khayran.

All praise be to Allah, and may His blessings and prayers be on His last messenger, Muhammad,

You should assume the truthfulness of people until proven otherwise. You can’t lead a sane life assuming the opposite. When offered food, the Messenger of Allah (blessings and peace be upin him) never interrogated people, Muslims or non-Muslim, regarding the source of that food or how they slaughtered their animals. Having said that, Muslims, collectively as communities, should have certification agencies to verify the wholesomeness of what is claimed in the market to be halal.

Allah knows best.
