Dought & clear, - Is it permissible to keep and train foxes and wolves and other predators?

I know that it is not permissible to keep a dog as a pet, but what
about foxes and wolves? It is known from years of experience that it
is possible to train these animals and live with them. What is the
shar'i ruling on that?.
Praise be to Allaah.
It is not permissible to keep and train foxes, wolves and other
predators such as lions and tigers, because there is no benefit in
that, and because keeping them may lead to great harm, as there is no
guarantee that they will not get loose and harm people. Moreover,
keeping them is a waste of money and spending on something
inappropriate. It is also an imitation of those spendthrifts who have
no ambition except satisfying their whims and desires.
Al-Nawawi (may Allah have mercy on him) said inal-Majmoo'(9/286-287):
The second category of animals is those in which there is no benefit,
so it is not permissible to sell them, such as dung beetles, scorpions
and snakes. ... Our companions said: that also includes wild animals
that are not suitable for hunting with or fighting, and cannot be
eaten, such as lions, wolves, tigers, bears and so on. Sales of such
animals are not valid, because there is no benefit in them. End quote.
Zakariya al-Ansaari (may Allah have mercy on him) said:
Sales of insects that are of no benefit are not permissible, and
neither are sales of wild animals that are of no benefit, such as
lions, wolves and tigers. The awe involved when kings keep such
animals and show that they can handle them is not regarded as being of
any benefit, unlike cases in which there is some benefit, such
leopards for hunting or, it was said, elephants for war. End quote.
Fath al-Wahhaab, 1/273
The Scholars of the Standing Committee for Issuing Fatwas were asked
about the shar'i ruling on dealing in or keeping animals that are used
to fulfil whims and desires, including predators such as wolves,
lions, foxes and so on.
They replied:
It is not permissible to sell predators such as wolves, lions, foxes
and other wild animals that have fangs, because the Prophet (blessings
and peace of Allah be upon him) forbade that. And because it is a
waste of money, and the Prophet (blessings and peace of Allah be upon
him) forbade wasting money. End quote.
Fataawa al-Lajnah al-Daa'imah, 13/38-21
It is well known that many of those who keep and train predators find
that the animal does not forget its wild origins and devours its
keeper, or attacks him or someone else.
There is a story that a Bedouin took a young wolf and raised it on the
milk of a sheep he had, and he said to himself: If I raise it with the
sheep, it will develop compassion towards it and will protect it, and
it will be better than a dog, and will not know the ways of its own
kind. But when it grew strong, it pounced on the sheep and devoured
it, and the Bedouin said:
You ate my little sheep although you grew up amongst us;
How did you know your father was a wolf?
Muhaadaraat al-Udaba', 1/115
And Allah knows best.
