Walaykumsalaam waa rahmatullahi respected sister,
I am sorry to hear about your loss, dear sister in Islam. May Allah azz zawajal make it easy for you and your family. Ameen.
May Allah subhaana wa ta'ala grant her Jannatul Firdaws and overlook all her shortcomings. Ameen.
Perhaps if you make a thread, more brothers and sisters will make dua for your beloved grandmother. I can do it on your behalf if you want me to.
My condolences to your parents, siblings and extended family. Inna Lillahi Waa Inna Alleihi Rajioon.
Wasalaamalaykum waa rahmatullahi
