On this: may he have intercourse with her by right of ownership?

Tawus said: Now she is his slave-woman.

Al-Hasan said: Now he may have intercourse with her by right of ownership.

Humayd bin Abd al-Rahman said: The first verse, {And lawful to you are those beyond these}, made her lawful, and the second verse, {until she marries a husband other than him}, made her unlawful. I neither command you nor forbid you.

Sa'id bin al-Musayyib said: He may not have intercourse with her by right of ownership. If he wishes, he may free her and marry her, and then he will be left with the right to only one divorce.

Qatadah used to act upon this view.

The same is reported from Sayyiduna Jabir (may Allah be pleased with him) and Abu Salamah.
