Dought & clear, - [Sacrifices], - Collecting the skins of the sacrificial animals, selling them and giving the price in charity.

The mosque committees here in Algeria collect the skins of the
sacrificial animals and sell them to leather manufacturing companies,
and they spend the money thus earned on building mosques, and they
argue that many people nowadays do not need them and they throw them
away. Is this action permissible? Is it permissible for a person to
give the skin of the sacrificial animal to them if they come to his
house and he knows beforehand that they are going to sell it?.
Praise be to Allaah.
Firstly:
It is not permissible for the one who offers the sacrifice to sell the
skin of his sacrificial animal, because it has been singled out for
Allaah in all its parts, and that which has been singled out for
Allaah is not permissible for anyone to make money from it. Hence the
butcher should not be given any of it by way of payment.
Al-Bukhaari (1717) and Muslim (1317) narrated that 'Ali (may Allaah be
pleased with him) said: The Messenger of Allaah(peace and blessings of
Allaah be upon him) commanded me to take care of his sacrificial
animals, and to give their meat, skins and blankets in charity, and
not to give the butcher any of it. He said: "We will pay him
ourselves."
It says inZaad al-Mustaqni': Its skin should not be sold, or any other
part of it, rather it should be made use of.
Shaykh Ibn 'Uthaymeen (may Allaah have mercy on him) said in
hisSharh(7/514): "Its skin should not be sold" after slaughter,
because it has been singled out for Allaah in all its parts, and that
which has been singled out for Allaah is not permissible for anyone to
make money from it. The evidence for that is the hadeeth of 'Umar ibn
al-Khattaab which says that he provided someone with a horse to ride
in jihad for the sake of Allaah, but the man to whom he gave it
neglected the horse and did not take care of it. 'Umar came and asked
the Prophet(peace and blessings of Allaah be upon him) for permission
to buy it because he thought that its owner would sell it cheaply, but
the Prophet(peace and blessings of Allaah be upon him) said to him:
"Do not buy it even if he gives it to you for a dirham." The reason
for that is that it was given for the sake of Allaah, and whatever a
person gives for the sake of Allaah, it is not permissible for him to
take it back. Hence it not permissible for the one who has migrated
from a land of shirk to go back and live there, because he left a land
that he loves for the sake of Allaah, so it is not permissible for
him to go back to something that he loves if he gave it up for the
sake of Allaah. And because the skin is part of the animal like the
meat, i.e., it is not permissible to sell it, just as it is not
permissible to sell its meat.
"or any other part of it" means that none of its parts may be sold,
such as the liver, leg, head, stomach and so on. The reason is the
same as that mentioned above. End quote.
Hence it is known that what is prescribed is to make use of the skin
or to give it in charity to one who deserves it, such as a poor or
needy person. But if the one who offers the sacrifice gives the skin
in charity to a poor person, and the poor person sells it, there is no
sin on either of them.
Shaykh Muhammad al-Mukhtaar al-Shanqeeti (may Allaah preserve him)
said: If there is a company that will buy the skins in the same
abattoir, and he gives it to a poor person, and the poor person goes
and sells it to this company, there is nothing wrong with that. End
quote fromSharh Zaad al-Mustaqni'.
Secondly:
With regard to selling the skins and giving their price in charity,
the scholars differed concerning that. Some of them said that it is
permissible and this is the view of the Hanafis and was mentioned in
one report from Imam Ahmad (may Allaah have mercy on him), but the
majority did not permit it.
It says inTabyeen al-Haqaa'iq(6/9): If he sells it for a few dirhams
to give them in charity, it is permissible, because it is an act of
worship like giving the skin and meat in charity.
Ibn al-Qayyim (may Allaah have mercy on him) said inTuhfat al-Mawdood
bi Ahkaam al-Mawloodp. 89: Abu 'Abd-Allaah ibn Hamdaan said
inal-Ri'aayah: It is permissible to sell its skin and offal and head,
and give the price in charity. This was stated by Imam Ahmad.
Al-Khallaal said: 'Abd al-Malik ibn 'Abd al-Hameed told me that Abu
'Abd-Allaah (i.e., Imam Ahmad) said: Ibn 'Umar sold the skin of a cow
and gave its price in charity.
Ishaaq ibn Mansoor said: I said to Abu 'Abd-Allaah: What should be
done with the skin of the sacrificial animals? He said: It should be
made use of and its price given in charity. I said: Can it be sold and
its price given in charity? He said: Yes, (because of) the hadeeth of
Ibn 'Umar. End quote.
See alsoal-Insaaf(4/93).
Al-Shawkaani (may Allaah have mercy on him) said inNayl
al-Awtaar(5/153): They were unanimously agreed that its meat may not
be sold, and the same applies to the skin. But al-Awzaa'i, Ahmad,
Ishaaq and Abu Thawr regarded it as permissible, and this is also the
view of the Shaafa'is who said: It should be disposed of as the
udhiyah itself is disposed of. End quote.
Based on this, there is nothing wrong with giving the skins to the
charitable organizations who will sell them and give their price in
charity. This is a charitable project, because most people do not make
use of the skins of the sacrificial animals, so selling the skins and
giving the price in charity is achieving the intended purpose, which
is to benefit the poor and avoid the haraam thing, which is offering
compensation to the one who offered the sacrifice for any part of his
udhiyah.
It should noted that the udhiyah may be given to the rich as a gift,
so if the one who offers the sacrifice intends that he is giving the
skin as a gift to the charitable organization which is collecting
them, there is nothing wrong with that. Then the charity may sell them
and give the price in charity however it wishes.
And Allaah knows best.
