Chapter: Tricks in marriages

Nafi narrated to me that 'Abdullah said that Allah's Messenger (ﷺ) forbade the Shighar. I asked Nafi', "What is the Shighar?" He said, "It is to marry the daughter of a man and marry one's daughter to that man (at the same time) without Mahr (in both cases); or to marry the sister of a man and marry one's own sister to that man without Mahr." Some people said, "If one, by a trick, marries on the basis of Shighar, the marriage is valid but its condition is illegal." The same scholar said regarding Al-Mut'a, "The marriage is invalid and its condition is illegal." Some others said, "The Mut'a and the Shighar are permissible but the condition is illegal."

`Ali was told that Ibn `Abbas did not see any harm in the Mut'a marriage. `Ali said, "Allah's Messenger (ﷺ) forbade the Mut'a marriage on the Day of the battle of Khaibar and he forbade the eating of donkey's meat." Some people said, "If one, by a tricky way, marries temporarily, his marriage is illegal." Others said, "The marriage is valid but its condition is illegal."
