[Ali Imran]

My point is since Islam allow the men to have 4 wives why would there be concubines. 4 wives is already one too many. There is no need for the men to have concubines.  If a married man like another girl and have not reach the limit allowed he can just marry her as his 2nd wife or 3rd or 4th.  No need for the forbidence of the word concubines in Quaran. Irrrelevant as I don't think the men wld have four wives.  In ancient China the dynasty era there are concubines. In the Malay dynasty are there?

When we marry a woman, coz we want her for that sex reason, we enter into an agreement. We agree to give the woman her rights as stipulated in the Shariah. This is called the nikah, done during the solemnization. I wonder if you have seen it. The agreement protects the woman.

When we take a mistress, we don't have to agree to anything. The man gets what he wants but the woman loses in the long run.

That is the difference. But yeah, we want that sex thing. I'm honest about it. I'm a regular man. I don't need to go for cardio at the gym. Sex is the best cardio.
