The validity of contracting marriage with two women simultaneously.
Chapter on What is Prohibited to Marry and Combining Between Them and Other Matters

Primary text
If a marriage contract is concluded with two women at the same time (two female slaves, or a free woman and a slave woman under the permissible view), the contract is valid for both. This is because contracting marriage with each one individually is permissible, thus combining them is also permissible, similar to marrying two female slaves.
