As salaamualeikum wa rahmatullahi wa barakatu,
Every so often I see someone post something against divorce and then someone else will come back saying that divorce is not haraam and depending on the circumstances it is fine to do. I recall ahadith about the punishments for divorce when it's done for the wrong reasons, but then I recall others where people divorced simply because they wanted to.
Since this issue comes up in different ways on different threads, I thought I'd ask the group to give examples of when a man or a woman asking for divorce is allowed in Islam, when, if ever, it is forbidden and when, if ever, it is preferred. Sources always welcome
