Islamic Marriage Rules: When Marriage Is Permissible or Forbidden

Egypt’s Dar Al-Ifta has issued several rulings regarding Islamic marriage laws, addressing common questions about marriage between relatives, non-Muslims, and polygamy, emphasizing that Islamic law sets clear boundaries to protect rights and ensure fairness.

Marriage Between Relatives and Breastfeeding Relations

Dar Al-Ifta explains that marriage is not allowed in cases where breastfeeding establishes a familial bond, as the foster child becomes similar to a biological child in terms of legal rulings.

Additionally, marriage is prohibited with close relatives explicitly mentioned in the Qur’an, such as nieces and descendants of siblings.

Marriage to Non-Muslims

Scholars clarify that marriage to non-Muslims is not universally permitted, especially with atheists or idol worshippers, as per Islamic legal rulings.

They also highlight that differences in belief and culture may significantly affect marital stability.

Polygamy in Islam

Al-Azhar’s Fatwa Center states that Islam permits polygamy under strict conditions of justice and financial capability.

It is not a requirement for the first wife to be informed for the second marriage to be valid, but transparency is strongly recommended to avoid social and family disputes.

Islamic marriage is built on principles of fairness, protection of rights, and family stability, following the clear guidelines established in the Qur’an and Sunnah.
