In Islam, the relationship between a brother and sister does not end with the latter's marriage. Marriage changes her circumstances, responsibilities and household, but it does not erase the bond of family. Their relationship may naturally change with time, but the responsibilities of kindness, respect, support and family ties remain.

Friday Musings

Islam gave women rights at a time when many societies treated daughters and sisters as burdens. The Quran strongly rejected such attitudes. Allah says: “And when the good news of the birth of a female child is announced to any of them, his face becomes darkened, and he is filled with sorrow.” — Quran 16:58

The verse describes an attitude Islam came to challenge. A daughter is not a source of shame. A sister is not someone who becomes less valuable simply because she is a woman.

Before marriage, a brother should treat his sister with dignity. He should not constantly belittle her, compare her with others or make her feel that she is less important than a brother. Being older or male does not give him permission to control, insult or humiliate her.

The Quran establishes a broader principle of good treatment: “Indeed, Allah commands justice, excellence, and generosity to relatives.” — Quran 16:90

The words “generosity to relatives” include the ordinary relationships within a family. Kindness should begin at home.

A brother should also protect his sister from harm, but protection should never become domination. Advising a sister with love is different from controlling every decision she makes.

Her Financial Rights

One of the most important areas where brothers must be careful is inheritance. Islam gave women a definite share of inheritance, and family members cannot simply take it away because they believe a brother deserves more.

Allah says: “For men is a share of what parents and close relatives leave, and for women is a share of what parents and close relatives leave, whether it is little or much—an obligatory share.” — Quran 4:7

This is a powerful statement. A sister's inheritance is her right. A brother cannot pressure her to surrender it, manipulate her emotions or use family relationships to deprive her of what Allah has assigned to her.

Marriage Does Not End the Relationship

After marriage, a sister may move into another home and become part of another family, but she does not stop being a daughter, sister or member of her original family.

Allah says: “Worship Allah and associate nothing with Him, and be good to parents, relatives, orphans, the needy, near and distant neighbours...” — Quran 4:36

Maintaining family relationships is therefore part of Islamic character.

A brother should continue to check on his married sister, visit her when appropriate, remember her on important occasions and be available when she genuinely needs help. He should not disappear from her life simply because she has married.

At the same time, maintaining a relationship does not mean interfering in her marriage. A brother should respect his sister's husband and her new household, while also remaining alert to serious injustice or abuse if his sister seeks help.

A Brother Should Not Become a Source of Pressure

Sometimes married sisters face pressure from their own families regarding money, property, family expectations or personal choices. A brother should never use emotional blackmail against his sister.

The Quran says: “Do not consume one another's wealth unjustly.” — Quran 4:29

This principle is particularly important when families deal with property and inheritance. Love between siblings should never be turned into a tool for financial exploitation.

Right to Maintain Family Ties

A sister also has the right to remain connected with her parents and siblings after marriage. Her husband may have responsibilities toward her, but marriage should not become an excuse to completely isolate her from her family.

Likewise, a brother should not expect his married sister to remain available for every family demand. Respect works both ways. She has her own household, responsibilities and circumstances.

The ideal relationship is therefore one of mutual understanding: a brother respects his sister's married life, and a sister respects her brother's responsibilities and circumstances.

Love Should Survive Every Change

The most beautiful brother-sister relationship is not one in which a brother controls his sister, nor one in which a sister depends upon her brother for every decision. It is one in which both grow into mature adults while preserving affection, respect and concern for one another.

Before marriage, a brother may be a companion and protector. After marriage, he can become a source of emotional support, wisdom and reassurance. But at every stage, he must remember that his sister is not his property. She is a person with dignity and rights granted by God.
