No, it is not halal (permissible) in Islam for a man to marry two sisters.
Islamic law prohibits marriage between certain relatives, and this prohibition includes marrying sisters. This is derived from interpretations of the Quran and the teachings of the Prophet Muhammad (peace be upon him).
Prohibited Marriage Partners
As stated in the provided reference, marriage is prohibited between a man and his:
- Sister
- Half-sister
- And other close relations like mother, aunt, grandmother etc.
Therefore, because a sister is explicitly listed as a prohibited marriage partner, marrying sisters is not halal.
