Praise be to Allaah.
In order for it to be permissible to eat chicken and meat
that is sold in Muslim countries and elsewhere, two conditions must be met:
The meat should have been
slaughtered in the manner prescribed in sharee‘ah; it should not have been
stunned with electricity, or drowned in water, or any other means of killing
that is done in some countries.
The one who slaughtered the
meat should have been a Muslim or a kitaabi (one of the people of the Book,
i.e., a Jew or Christian); it is not permissible to eat meat slaughtered by
a communist, atheist or idol-worshipper.
See the answer to question no.
If it becomes clear to you that the chicken sold in these
restaurants has not been slaughtered in the manner prescribed in sharee‘ah,
it is not permissible for you to eat it and it is not permissible for you to
work with those who sell it, because that comes under the heading of
cooperating in sin and transgression.
It is permissible to eat fried meat and fish from these
restaurants, subject to two conditions:
That it is not fried in the
same oil as the non-halaal chicken or in vessels in which chicken was fried,
until they have been washed, because the non-halaal chicken is maytah (dead
meat) and is najis (impure).
The meat should be halaal.
And Allah knows best.
