SHAFAQNA (Shia International News Association) – If we look at our actions we can find many mistakes and sins in our lif time which some of them become habit inside us. So it is important to find out how committing sin can become a habit and send a person to hell for ever. Apart from the divine prophets and 14 infallibles who are free from sins and mistakes, no other person can be like them. This means that the possibility of committing sins are there for human beings but this situation can exist in two ways; with prior intention and choice or unwittingly and through carelessness. If a person committ a sin with prior intention and regularly, then gradually that sin will fill his inner self and becomes a habit. Ayah 81 of Surah Al-Baqarah said: Yes, those who commit sins and the effects of sins fill their inner selves, they are fit for fire and will remian in it for ever. Therefore, at anytime, if we want to commit a sin, it is best to remeber this Ayah immediately in order to stay away from hell fire.
