What difference does it make? The girl is no more. You cannot kill your own children for something they did not do. Agreed that there might be more to the story but the bottom line is that the girl is no more and father is the one that killed her. For the sake of argument, I agree that the father might’ve repented afterwards and Allah knows best whether He will forgive the father or punish him in the hereafter as Allah is Raheem ul Kareem but we should be making duas for the girl that may Allah forgive her and admit her in Jannah. Baat khatam.
