Is it permissible for my wife to leave the house and be late in returning, even though I do not want her to go out except with me, due to my jealousy for her and my fear of intermingling in the street?

The wife is obligated to obey her husband and not to leave the house except with his permission, unless there is a necessity. If he permits her, she should not delay beyond the specified time. The evidence for this is the hadith: "Do not prevent the female servants of Allah from the mosques of Allah," which indicates that the husband has the right to prevent his wife from leaving, and that she should not leave except with his permission.
