Finding Solace After Losing a Beloved Pet

A few days back, my six-year-old cat, who was like family to us, passed away after a sudden illness. He was such a joyful companion, and it's hard to put into words how much he meant to us, especially to my mother who's deeply grieving right now. We're trying to ease our hearts by reminding ourselves that this is all part of Allah's plan, repeating it together as a source of comfort. It's tough not to tear up when we think about him, and even with tawakkul, it feels overwhelming when I see the spots where he used to nap and play. I buried him with a promise that we'd reunite in Jannah. Does that really happen? How do others manage to cope with this kind of loss?
