Ata (may Allah have mercy on him) said that a woman said to the Prophet (peace and blessings be upon him): "I hate my husband and I want separation." He (peace and blessings be upon him) said: "Will you return the garden that he gave you as dowry (mahr)?"
The narrator said that her dowry was a garden. She said: "Yes, and I will give him more than that as well." He (peace and blessings be upon him) said: "The extra is your own wealth; just return the garden." She said: "Very well," and he (peace and blessings be upon him) gave his judgment. When he (the husband) was informed of the judgment of the Prophet (peace and blessings be upon him), he said: "I accept the judgment of the Prophet (peace and blessings be upon him)."
