Hadith No: "A hypocrite fighting alongwith Rasulullah (saw) was very brave in the fight but when he was too much hurt, he killed himself with his own sword to avoid pain. Upon this, Rasulullah (saw) informed all that this person goes to hell. He said that there are some who do a few things to qualify for heaven, but they actually qualify for nothing except hell. Similarly, there are some whom everyone considers as going to hell, but they are actually going to heaven." (Muslim).
