If a slave-girl is freed and at the time of the gift her husband is present, then this gift is permissible, but the condition is that the woman should not be of unsound mind. Because if she is of unsound mind, then it will not be permissible. The statement of Allah, the Exalted, is: «ولا تؤتوا السفهاء أموالكم‏» "Do not give your property to the foolish."

Narrated Asma: Once I said, "O Allah's Apostle! I have no property except what has been given to me by Az-Zubair (i.e. her husband). May I give in charity?" The Prophet said, "Give in charity and do not withhold it; otherwise Allah will withhold it back from you . "
