No body gonna protect you from Allah except Allah ,

How you would replay to Allah when you know that you've abandoned the teaches of Mohamed ( The connection of Allah and his peace upon him ) !!!!!

You follow yourself then you followed yourself
You Follow Mohamed (s) then you followed Allah .

It's up to you

and about 4 wifes ...

Mohamed the passenger of Allah (s) didn't marry others while he was married with Khadeja (r).
Seems like he admired more than we ever know for Khadeja (r)

While after she (r) died he (s) married others .
Friends of Mohamed (s) also had married more than one .
they made families , they wanted children to carry on this massage of Allah .

It is a virtue to marry more than one wife to make the word of Allah the highest .
this verse explains one of the reasons to be able to marry more than one .
and it doesn't forbid to marry more without having orphans ...
