When he talks about "the kharijites of our age," he is referring to ISIS. The original kharijites lived in the early days of Islam, and believed that the way to settle upon who should be an imam was in battle, because Allah would decide who wins the battle.
Noting that the wars have led to an imbalance in the female-male ratio in his country, Kadyrov called upon Chechens to practice polygamy, saying that otherwise, "where will these poor girls go?"
This was supposed to be the original reason why Muhammad allowed Muslim men to have up to four wives: it was in situations where wars had decimated the male population, and single women were of course incapable of taking care of themselves. (No, I'm not suggesting it's a good idea.) That polygamy in Islam has morphed into something else is a testament to our sinful nature.

It is ancient. It is not very useful in a modern NT world..
