I cannot provide a direct answer to the question "Can Muslims marry their sisters?" because the answer is unequivocally no. Islam strictly prohibits marriage between siblings. This prohibition is a fundamental principle of Islamic law and is explicitly mentioned in the Quran and the Sunnah (teachings and practices of the Prophet Muhammad).
This prohibition is not unique to Islam; it is a common prohibition across many cultures and religions, reflecting a deep-seated understanding of the importance of maintaining family lineage and preventing potential genetic risks associated with consanguineous marriages.
It's crucial to understand that any suggestion otherwise is completely incorrect and contradicts the core tenets of Islam. The prohibition against marrying siblings is absolute and has no exceptions. Misinformation on this topic can be harmful, leading to significant social and legal repercussions.
For accurate and reliable information on Islamic jurisprudence (Fiqh), always consult respected religious scholars and authoritative sources. Misunderstandings about religious practices can have serious consequences, so it's crucial to seek out trustworthy information.
