But like some other major sins, it does not ultimately drop one out of the religion of Islam, (Yet repentance is a must in most cases) and it does not eternalize the doer in the Fire of Hell. God the Almighty said in the holy Qur'an: (God may forgive sins to any extent only if he pleases, except when it comes down to committing Shirk [1]. Shirk is an unforgivable sin and one who commits Shirk with God, does indeed commit a horrendous serious sinful lie).
