Ruling on Muslims and kaafirs leaving things to one another in their wills

The Hanafi, Hanbali and most of the Shaafa’i fuqahaa are agreed
that it is OK for a Muslim to leave something to a dhimmi (non-Muslim living under Islamic
rule) in his will, and vice versa, so long as this is within the guidelines of
shareeah. Their evidence for this is the aayah (interpretation of the meaning): Allaah
does not forbid you to deal justly and kindly with those who fought not against you on
account of religion and did not drive you out of your homes. Verily, Allaah loves those
who deal with equity. [al-Mumtahinah 60:8]. Also, being a kaafir does not
disqualify a person from ownership, and as it is OK to sell to a kaafir or give him a
gift, it is also OK to include him in ones will.

Some of the Shaafais think that it is OK only if a specific
person is named, such as saying I leave [such and such] to so and so; but if a
person says I leave [it] to the Jews and Christians, this is not OK because it
sounds as if he is making their kufr the reason for leaving something to them. The
Maalikis agree with others that it is OK for a non-Muslim to leave something to a Muslim.
With regard to a Muslim leaving something to a non-Muslim, Ibn al-Qaasim and Ashhab said
that it is allowed if it is done for a reason, such as upholding family ties, otherwise it
is makrooh, and should not be done at the expense of a Muslim. No one would do such a
thing except one whose faith is diseased.

(al-Mawsooah al-Fiqhiyyah,
2/312)

Unfortunately, nowadays we see some Muslims, especially
those who are living in kaafir countries, leaving huge sums of money to Christian, Jewish
or other kaafir organizations, on the basis that these are charitable, educational or
humanitarian organizations and so on, but there is no way that Muslims can benefit from
this. The only ones who benefit from it are the kuffar, and their hungry oppressed refugee
Muslim brothers are left with no h elp or support. This is a sign of weak, diluted faith
and of allegiance to and admiration of the kuffaar and their disbelieving societies. We
ask Allaah to keep us safe and sound. May Allaah bless our Prophet Muhammad.
