Please see the following old thread http://www.sunniport.com/masabih/showthread.php?t=2674&highlight=misyar This practice seems to have been encouraged only by wahabis.
:s1: I was watching an Islamic discussion program on DM Islam last night and some caller rang in and said that some ulama in Egypt and Saudi Arabia have given a fatwa that a type of temporary marriage, which he called 'misyaar' is allowed? I was surprised as I thought mutah' was forbidden by Sunnis. Is nikah e misyaar something different?
