Well the chicken was probably killed by a christian or a jew and the vegetables already come cut and trust me, I make the fries and nobody dumps a sausage in the fryer for the fries. And also buger king as actually a very clean place.
Asalamu alaikum akhi wa oukhti
There is one little thing here what need some attention...
It is truth that we can eat (cow, chicken) meat slaught by jahudi or christian.
BUT!!! on a few conditions!!!! That the jahudi or christian slaught the meat on the islamic way with the islamic rituals
"And the food of those who have been given the Book is lawful for you and your food is lawful for them" (5:5).
This is the qoranic proof that we can
But since i don't know any big food company in the west like McD and KFC and Burger king who does this type of slaughtering it is better to stay away from it.
BUT NOW....
More important information to stay away from it
“Hafiz ibn Jawzi (RA) has narrated with his Sanad (chain of narrators) from Ali, Radi-Allahu anhu, 'Do not consume the slaughter of the Christians of Banu Taghlib since they have not held to any more of Christianity than their drinking of wine.'” (Ibid pg.460 - from Tafseer Mazhari)
From this hadeeth and others we can learn that most of the christian and jahudi become Mushrikoen or atheists.
Like christians who said that Isa as is the son of Allah swt or pray to maryam (mary) this is no christianity those people are mushrikoen
the same story for jahudi.
So the change that a fabric of producing food for those big food company's has a staff of people who are righious christian or jahudi is so smal , I won't count on it..
the best thing is to stay away from those big food company's in the west.
If anything is wrong from what i say its from me and not from allah swt
May allah guide us to siraatul mustaqeem and make from us the people of djennah
Excuse me for my bad english i'm not a native engelish person
Wa alaikum salam
