Benefit:
Shaykh al-Islām, may Allah have mercy on him, said: “As for coitus interruptus (ʿazl), some scholars have declared it forbidden; however, the position of the four Imams is that it is permissible, provided the wife gives her consent.”

Second benefit:
He also said: “Once a woman is married, her husband has greater authority over her than her parents, and obedience to him is more binding upon her. She is not allowed to leave his house without his permission, even if her father or mother orders her to do so—this is agreed upon by the leading jurists. If the husband wishes to move with her from one place to another while fulfilling his obligations toward her and observing Allah’s limits, yet her father forbids her to comply, she must obey her husband rather than her parents. In that situation the parents are acting unjustly; they have no right to prevent her from obeying such a husband.”

Chapter: The Prohibition of Being Alone with a Non-Mahram Woman

ʿUqbah ibn ʿĀmir reported that the Messenger of Allah ﷺ said, “Beware of entering upon women.” A man from the Anṣār asked, “O Messenger of Allah, what about the ḥamw?” He replied, “The ḥamw is death.”

Muslim relates—through Abū al-Ṭāhir, from Ibn Wahb—that al-Layth said: “The ḥamw is the husband’s brother and whoever resembles him among the husband’s male relatives, such as a paternal cousin and the like.”

Unfamiliar terms:
• Iyyākum (beware): the direct object of an implied verb, meaning “guard yourselves against entering.” In syntax this is called naṣb ʿalā l-taḥdhīr—alerting the addressee to a danger so he may avoid it. The full sense is: “Protect yourselves from entering upon women, and protect women from entering upon you.” The word “entering” (dukhūl) is coordinated with the elided object.
• “What about the ḥamw?”—that is, “Tell us the ruling on the husband’s in-law being alone with her.”
• Ḥamw: with an open ḥāʾ, a ḍamma on the mīm, and a final wāw, not hamzah. It denotes the husband’s male relatives—brother, paternal cousin, and so forth. Al-Nawawī said: “The linguists agree that aḥmāʾ are the wife’s in-laws on her husband’s side, such as his father, uncle, brother, paternal cousin, and the like.”
