This is a followup question to another popular question here: Does Islam support pedophilia or child marriages?
A lot of the answers say, age is not a consideration in marriage, since the time of consummation (which is when puberty starts) is separate from marriage and can be years apart.
The example given in the example in previous question was, Muhammad married Ayesha when she was 6, but they did not consummate the marriage until she was 9, which, presumably is when she began puberty. (Let's forget the argument as to whether a pre-pubescence child can consent to marriage).
So what are the qualities people look at in marriage? Just family unions and relations and religious ties? Or is love in the equation, and what kind of love?
