Answered by: Maulana Syed Johir Miah
Can a Muslim family help out a Christian family financially for the burial of their mother?
In the name of Allah, the Most Gracious, the Most Merciful
It will be permissible to visit a non-Muslim to offer one’s condolences for a family bereavement. It is not permissible to give Zakah to the non-Muslims, however, sadaqah can be given to them to aid in the burial of their mother.
Only Allah knows best
