Dought & clear, - Sacrifices, - Ruling on sacrificing camels other than an’aam animals.

A person lives at the North Pole and wants to offer a sacrifice. Is it
permissible for him to sacrifice a fish?.
Praise be to Allaah.
It is not valid to sacrifice a fish, horse, deer or chicken, because
one of the conditions of sacrifice is that it must be one of the
an'aam animals, which are camels, cattle and sheep of all kinds,
because Allaah says (interpretation of the meaning):
"And for every nation We have appointed religious ceremonies, that
they may mention the Name of Allaah over the beast of cattle [an'aam]
that He has given them for food"
[al-Hajj 22:34]
It is not reported that the Prophet(peace and blessings of Allaah be
upon him) or any of his companions sacrificed any other kind of
animal.
See:Fath al-Qadeer(9/97).
Al-Nawawi said inal-Majmoo'(8/364-366):
The conditions of a sacrifice being valid include that it should be
one of the an'aam animals, which are camels, cattle and sheep. All
kinds of camels, cattle and sheep, including goats, are acceptable.
Other kinds of animals, such as wild cattle, donkeys etc are not
acceptable, and there is no difference of scholarly opinion on this
point, whether male or female of all kinds, there is no difference of
opinion on any of that in our view.
A cross between a deer and sheep is not acceptable, because it is not
an an'aam animal. End quote.
Ibn Qudaamah (may Allaah have mercy on him) said something similar
inal-Mughni(368).
Shaykh Muhammad ibn Saalih al-'Uthaymeen (may Allaah have mercy on
him) said in his essayAhkaam al-Udhiyah wa'l-Zakaah(rulings on
sacrifice and zakaah):
The type (of animal) that may be sacrificed is an'aam animals only,
because Allaah says (interpretation of the meaning):
"And for every nation We have appointed religious ceremonies, that
they may mention the Name of Allaah over the beast of cattle [an'aam]
that He has given them for food"
[al-Hajj 22:34]
The an'aam animals are camels, cattle, sheep and goats. This was
stated by Ibn Katheer who said: This was the view of al-Hasan,
Qataadah and others. Ibn Jareer said: This is how it is among the
Arabs. End quote.
And the Prophet(peace and blessings of Allaah be upon him) said: "Do
not sacrifice anything but a musinnah; if one is not available then
sacrifice a jadh'ah sheep (one that is over a year old)." Narrated by
Muslim (1963). A musinnah is a camel, cow or sheep that is two years
old or older. This was the view of the scholars (may Allaah have mercy
on them).
The sacrifice is an act of worship, and it should not be done except
in the manner narrated from the Messenger of Allaah(peace and
blessings of Allaah be upon him), and it is not narrated that he(peace
and blessings of Allaah be upon him) sacrificed anything but a camel,
cow or sheep.
