Answer
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
In this fatwa:
Your great grandfather’s inheritance should be divided among his children who were alive at the time of his death including your mother.
In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states:
I will assume that your great grandfather died while all his children were alive which means your mother’s dad should have inherited like his brothers and sisters.
Now if they did not distribute that property because of being unaware and then your mother’s dad died, the uncles and aunts of your mom should honor their brother’s share and give it to his children including your mom.
Please, ask a local Islamic court or Imam who can ask more clarification questions on that matter for I only spoke of a ruling based on assumption. More details are needed if you seek a detailed reply.
Almighty Allah knows best.
