Is a man considered a Muuli if he swears, 'By God, I will not have intercourse with you in the anus'?
General Chapter
Al-Mughni
Book of the Oath of Abstention (Ila')
Primary text
A man who swears, 'By God, I will not have intercourse with you in the anus' is not considered a Muuli. This is because he has not refrained from the intercourse that is obligatory upon him, nor does the wife suffer harm from its omission, as intercourse in the anus is forbidden.
