Dear sister in Islam
Wa'laikumus-salam

If a child has no mother, or she has refused to take the child, the right to foster the child shall devolve in this order. Firstly the maternal grand mother and maternal great grand mother; then grand mother and great grand mother; then real sisters of the child and step-sisters----preference will be to those sisters whose and child's mother is the same and then those sisters whose and child's father is the same; then mother's sister and lastly father's sister.
