Legal heirship advice as per India sunni muslim law

Need advice on the my Meternal grandma's Father property and their legal heir-ship. Just to give some background information, we basically belong to Sunni India Muslim tribe. My grandmas's father bought a property in 1953 and registered it in his name. He executed a will on 1982 is as follows "I have executed this gift deed is that 1st one is my daughter, second one is my daughter's son, thus grand son to me. Having love and affection towrards you, for your future life interd to provide some propery to you, with this opinion, at free of cost the propery worth Rs 10,000/- gifted to you and provided the rights over it, thus hence forth the scheduled property during my life tenure possess and enjoy the same and after my after me 1st one (Daughter)A without making any transactions over it with rights and after her death, 2nd of us (Grand Son)B should possess and enjoy holding full rights over it. In the matter, either by me or my heirs will not hold any rights over it. This gift Deed is executed by me with my own consent." Subsequently, my grandmother's father passed away during 1982, his Daughter's Son (Grand Son) Passed away in 1996 and my grandma died very recently. She did not leave any will for her property. There are 2 daughters to my grand grand father having no son. my Grand mother has one Son and one Daughter both are passed away before my grand mother. My grand mother's Son has 3 children and Daughter has 4 children. Now who will be the legal hairs of this property. Will it be succeeded to us or will it be devolves to my grand mother sister who is alive today.
