Praise be to Allaah.
It is not permissible for a man to be married to two
sisters at the same time or to a woman and her paternal or maternal aunt
at the same time, because Allah says
(interpretation of the meaning):
“Forbidden to you (for marriage) are: your mothers, your
daughters, your sisters, your father’s sisters, your mother’s sisters, your
brother’s daughters, your sister’s daughters, your foster mothers who gave
you suck, your foster milk suckling sisters, your wives’ mothers, your
stepdaughters under your guardianship, born of your wives to whom you have
gone in — but there is no sin on you if you have not gone in them (to marry
their daughters), — the wives of your sons who (spring) from your own loins,
and two sisters in wedlock at the same time, except for what has already
passed; verily, Allaah is Oft‑Forgiving, Most Merciful”
Shaykh ‘Abd al-Rahmaan al-Sa‘di (may Allah have mercy on him)
said in his Tafseer (1/173): These verses refer to those who are
haraam in marriage because of blood ties, those who are haraam because of
breastfeeding, those who are haraam because of ties through marriage, those
who are haraam because it is not permitted to be married to them and another
woman at the same time, and women who are permissible in marriage.
With regard to those who are haraam because it is not
permitted to be married to them and another woman at the same time, Allah
mentions being married to two sisters at the same time and describes it as
haraam. And the Prophet (blessings and peace of Allah be upon him) forbade
being married to a woman and her paternal or maternal aunt at the same time.
So if we take a pair of women who are related to one another, if we imagine
that one of them is male and the other is female, if it would be haraam for
them to get married, then it is haraam for them to be co-wives. That is
because of what would result from that of severing ties between relatives.
Al-Bukhaari (5109) and Muslim (1408) narrated from Abu
Hurayrah (may Allah be pleased with him) that the Messenger of Allah
(blessings and peace of Allah be upon him) said: “One should not be married
to a woman and her paternal aunt, or a woman and her maternal aunt, at the
Ibn Qudaamah (may Allah have mercy on him) said, explaining
the women who are forbidden in marriage: “married to a woman and her
paternal aunt, or a woman and her maternal aunt, at the same time” - Ibn al-Mundhir
said: The scholars are unanimously agreed on this matter and there is no
difference of opinion concerning it, praise be to Allah, except that some of
the innovators whose difference of opinion does not count, namely the
Raafidis and Khawaarij, do not regard that as forbidden and they do not
follow the Sunnah that is proven from the Messenger of Allah (blessings and
peace of Allah be upon him), as it says in the hadeeth of Abu Hurayrah
The reason for the prohibition on being married to two
sisters at the same time is that it would cause enmity among relatives and
lead to severing the sacred ties of kinship, and this reason is also
applicable in the case of marriage to a woman and her maternal or paternal
aunt at the same time.
If they quote as evidence the general meaning of the words of
Allah (interpretation of the meaning): “All others
are lawful,” [al-Nisa’ 4:24], then the report we
have narrated makes exceptions from that. End quote from al-Mughni,
