After seeing the funeral of 160 innocent girls, if you still do shia-sunni at this point, you are siding with the one who killed them. There is no middle ground here
I’m touched by the saying;
"If Allah allows you to keep making dua for something, it means He wants you to have it. keep asking & remember He is Al-Wahab- giver of all things."
Just pray.
"Zakariyaa A.S didn't know how Allah was going to give him an offspring. He, still prayed.
Yunus A.S didn't know how he would be saved from the belly of a whale. He still prayed.
Musa A.S didn't know how Allah will make out a way from a dead end. He still prayed.
