All praises are due to Allaah and peace and blessings, be upon His prophet Muhammad and his family and companions Allaah, the Almighty created the human Nafs (self or soul) with two main strengths, which are: the strength of advancement and the strength of restraint. The strength of advancement must be directed to the things that are of benefit to the person in this life and the Hereafter. As for the strength of restraint, this must be used to abstain from what harms the person. The Muslim should naturally be disposed to advance in good and restrain from evil. This restraint is like a rein that holds the Muslim back from all evil. Therefore, restraint is the Muslim's curb which prevents him from committing or indulging in evil, sins and non-beneficial matters. The stronger the restraint is, the better the Muslim can oppose his forbidden desires, temptations and trials. Some people have patience with the discomfort of worship but have no patience when it comes to avoiding sins, and vice versa. For example, many people have the patience to stand in night prayers in the cold and heat, and have patience with the discomfort of fasting, but do not have the patience to restrain themselves from gazing at what is forbidden. Many other people have the patience to restrain from indulging in the forbidden gaze, but do not have the patience to enjoin good and forbid evil or to combat the disbelievers and hypocrites. 1 However, the best people are the ones who have patience with both categories.
