Killing a lizard
Q: Today, my mother ordered my to kill a lizard that was in our house. It was the size of an index finger. I truly hate killing insects and pests and prefer to just take them outside. But in the heat of the moment I killed it. I am feeling very bad about it because I value life of other beings. I am still feeling bad about it. I really want to forget that but I cant. Is what I did haram?
