Assalam alaikum, Dear scholars, I am a fema le medical school student and we are doing human dissection.  I am at school at duhr prayer and would like to pray, especially the friday jamaah prayer... Is it okay to only do wudu or is it necessairy to do ghusl since we're touching a dead body (which happens to be a male). Insha ALlah you can englighten me on this issue.. Jazakum ALlah khair
