In Islam, conscientious restraint from committing sins is essential for achieving a life of good character. This concept is known as "istiqamah" or "keistiqamahan". Istiqamah refers to a state in which one persists steadfastly in observing Allah's commands and staying away from His prohibitions.
In this context, conscientious restraint means that one takes the necessary steps to avoid committing sins. This involves a heightened awareness of the acts forbidden in Islam and a persistent effort to avoid committing such sins.
Conscientiously refraining from committing sins also involves strict self-monitoring and control of passions. It requires a deep awareness of the possible negative consequences of committing a sin as well as a willingness to sacrifice immediate gratification for long-term good.
This practice also requires a deep knowledge of Islamic religious laws and a proper understanding of moral values. By understanding the teachings of Islam thoroughly, one can make wise decisions and avoid actions that go against religious principles.
Through perseverance in refraining from committing sins, one can improve his relationship with Allah and achieve a more harmonious and meaningful life. It also helps the individual to develop the self-strength, fortitude and discipline necessary to lead a life of high morals and achieve spiritual perfection.
