Sahih Muslim | Book 8 | Hadith Number 3275

Narrated by Abu Huraira (Allah be pleased with him)
Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) forbade the combining of a woman in marriage with her father's sister, or with her mother's sister, or that a woman should ask for divorce for her sister in order to deprive her of what belongs to her. Allah, the Exalted and Majestic, is her sustainer too.
