The Janaazah salaah on half a body

Q: Janaa'iz-54: What is the ruling with regard to the Ghusl, Kafan and janaaza salaah of a person whose body is only half or less left?

Answer: When the half body includes the head, it will be regarded as a full Body. it will therefore be bathed and shrouded and the Janaazah salaah will be performed. If the half body is without the head, there is no necessity for bathing, shrouding and burial. It will be washed, wrapped in a cloth and buried in a hole. The same applies to a body that is less than half its size. And Allaah knows best what is most correct.
