Shaikh, what are my responsibilities to my step-mother and my full siblings after father passed away? I fear the punishment of allowing free-mixing, and also other sins, in our rented apartment. Would I be held accountable? What would you advice me, Shaikh?

Ustadh AbdulAziz al-Haqqan

You are not the father, so your mother and those who are senior like grand parents and uncles etc, can advise, instruct, and take action.
