Q:

When a Husband dies who is responsible for the wife? (young newly wed couple) Will it be the groom’s side of the family or bride’s side of the family? who will get her remarried and when can she remarry?

A:

When a husband dies, his widow should observe iddah or waiting period of four months and ten days. During which time she should be looked after by the groom’s family; once the period has expired, she should be moving to her family; it is their responsibility to support her and help her to get married.

Almighty Allah knows best.
