1. A Muslim inherits from a non-Muslim, but a non-Muslim does not inherit from a deceased Muslim, even if he be his/her father or son. If some of the heirs are Muslims and some are non-Muslims, only the Muslim heirs inherit from him/her. Also, a Muslim inherits from a Muslim irrespective of whether he/she is Shia or Sunni.
2. If the heirs of the deceased is one maternal aunt or one paternal aunt (regardless of her being full paternal or maternal aunt (that is, they are from the same parents) or related from father's or mother's side, all the properties will be inherited by her. Now if the deceased had been a woman and her husband is alive, her properties are divided among her paternal or maternal aunt and her husband equally.
