Is it acceptable to stipulate a condition in the marriage contract that her husband should not inherit from her if she dies?

 

If a wealthy widow with children decides to remarry, can she put a clause in the marriage contract saying that after her death only her children will inherit from her and her new husband will give up any inheritance rights?

 

Praise
be to Allaah.

The basic principle with regard to contracts and conditions
is that they are permissible and valid, and none of them are haraam or
invalid except that which is contrary to sharee‘ah. 

Stipulating that the husband should be deprived of inheriting
in the event of the wife’s death is a condition that is contrary to
sharee‘ah, because it is cancelling out the right of the husband that Allah
granted him to a share of his wife’s wealth in the event of her death. 

Al-Bukhaari and Muslim (1504) narrated from ‘Aa’ishah (may
Allah be pleased with her) that she said: The Messenger of Allah (blessings
and peace of Allah be upon him) said: “What is the matter with people who
stipulate conditions that are not in the Book of Allaah? There is no
condition that is not in the Book of Allaah but it is invalid, even if there
are one hundred conditions. The Book of Allaah is more deserving of being
followed and the conditions of Allaah are more binding.” 

Al-Qurtubi (may Allah have mercy on him) said: 

i.e., conditions that are not acceptable according to
sharee‘ah are invalid even if they are many.

Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him)
said: 

Whoever stipulates conditions in a waqf, manumission, a gift,
a sale, a marriage contract, rental, vow and so on that is contrary to what
Allah has decreed for His slaves in that those conditions enjoin something
that Allah has forbidden or forbid something that Allah has enjoined, or
they permit something that He has prohibited or prohibit something that He
has permitted, then these conditions are invalid according to the consensus
of the Muslims of all eras.

He also said: 

If a condition is contrary to the conditions of Allah and His
Messenger, it is invalid, such as if he stipulates that his son or his
relatives should not inherit from him, or that he should help him in
everything he wants and support him against everyone who opposes him whether
he is in the right or otherwise, or that he should obey him in everything he
tells him to do, and other such conditions. 

And when such conditions are made, then one should fulfil the
part of it (the contract) that is in accordance with the commands of Allah
and His Messenger (blessings and peace of Allah be upon him), and he should
not fulfil the part that is contrary to that. This is agreed upon among the
Muslims.
