Asking for a separation

Q: My husband is having an affair with other women, which he refuses to break relations with. He is a very abusive man who abuses me emotionally, mentally and physically. We have 2 children together who have witnessed all the abuse. Do I have grounds for a divorce and what are they?

Cupping

Q: I have heard that cupping is sunnat, and have also heard that cupping is not Sunnat. Which is the correct view? I was under the impression that all that Nabi Sallallahu Alaihi Wasallam advised or did was Sunnat. Please can Mufti Saheb explain why cupping is not Sunnat and how things get classified as Sunnat?
