Why do musims marry more than once?

its dere in quran they can marry women who r widows..its misinterpretted as polygamy...

No it is a great mis-understanding about islam..... Yes our religion permits four marriages.. maximum at a time.... but with few conditions.... which are... one must do just with all the wives.... through giving them equal facilities equal time.. equal rights.... equal status... and if one cant fulfil the conditions.... marrying more than one is not allowed in any case..... No all muslims do four marriages...... there are rare cases.... howeve..... since this is allowed ... few riches ... utilize this permission for vested interest... which is totally against islam..... there are few other reasons.... islam allowed for four marriages at one time........

They must be having spares.

they religion allows it.

I guess they enjoy wedding ceremonies? Or maybe some of our Musim Brothers/Sisters would be able to give some good thelogical explanations.

because their religion permits polygamy..
