Praise be to Allaah.
If you are not sure about this meat and think that it may be
pork, then it is not permissible for you to serve it to the children.
But if you know that it is permissible meat such as beef or
lamb, but you are not sure whether it was slaughtered in accordance with
Islamic sharee’ah or not, then it is halaal and no attention should be paid
to this uncertainty, so long as the one who slaughtered it was one whose
slaughter is valid, namely a Muslim, a Christian or a Jew.
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said:
If this meat comes from one whose slaughter is permissible,
then it is halaal, and we do not have to ask how it was slaughtered or to
ask whether the name of Allaah was mentioned over it or not. We do not have
to do that and indeed we should not do that, because asking about this comes
under the heading of exaggerating about religious matters. Hence when people
came and asked the Prophet (peace and blessings of Allaah be upon him),
“People bring us meat, and we do not know whether they mentioned the name of
Allaah over it or not?” He said: “Say Bismillaah yourselves and eat.” He
said not say: Ask them; he said: “Say Bismillaah yourselves and eat.”
‘Aa’ishah (may Allaah be pleased with her) said, narrating this hadeeth,
They had recently become Muslim, and the one who has only recently become
Muslim may be unaware of the necessity of saying Bismillaah when
Whatever the case, if meat comes to you from people whose
slaughter is permissible – and those whose slaughter is permissible are
three types of people: Muslims, Jews and Christians – then do not ask.
The Jews used to give gifts of meat to the Prophet
(peace and blessings of Allaah be upon him) and he would eat it without
asking about it. The Jews would invite him to eat barley bread and fat, and
he did not ask about this fat and how the animal it came from was
slaughtered. The best of guidance is the guidance of Muhammad (peace
and blessings of Allaah be upon him). End quote.
