Are you implying, the sahabas during the time of Prophet P.B.U.H practicing prosititution. So far no one has rejected Muatah was not practicced during the lifetime of Prophet P.B.U.H so far the argument has been was it Hazrat Umar who had outlawed it or Prophet .. after some time… but it was something that has been there during the time of Prophet P.B.U.H. Who are you to judge a practice that was allowed in the time of Prophet to compare it with a lowly act
Unlike Prosititution, the woman is well protected and any kids born from Mutah get inheritance from dad and so on. Mutah is quite similar to a normal marriage. Like the nikkah the guy and girl have to recite a siggah for the marriage. If a concept of temporary marriage is not acceptable in islam, why would the clause of divorce be allowed in islam to begin with? A guy and girl can marry each other share a halal relationship and than have a divorce.. divorce is acceptable in islam isnt it.
