Euthanasia

what is the islamic view on 'mercy killing?'

Dear scholars, As-Salaam `Alaykum. I would like to know the Islamic stance on euthanasia. Jazakum Allah khayran.

Nowadays, there are many different rulings concerning Islam’s stance on euthanasia. I am really confused and would like you to furnish me with a detailed fatwa regarding the different types of euthanasia and the Islamic ruling regarding each.
