Ameer al-Momineen (a.s) said: “Abstinence is a form of wealth. Piety is like an armor. Abstinence is best when done in private. Abstinence will make the body slim and restrict aspirations, and speeds up death and pushes away worldly desires. Whoever attains it benefits, and whoever loses it will be burdened. Nothing is nobler than piety. No trade is better than the performance of good deeds. Nothing is a better form of piety than abstaining from what is doubtful. Nothing is a better form of abstinence than abstaining from the forbidden. In short abstinence is expressed by God's statement: “In order that ye may not despair over matters that pass you by, nor exult over favors bestowed upon you.” [The Holy Quran: Hadid 57:23] Therefore whoever does not worry about the past, and does not get happy about the future has realized both aspects of abstinence. O' people! Abstinence implies reducing aspirations, and thanking God for the blessings, and abstaining from the forbidden. Whenever you lose these characteristics, do not let the forbidden acts overcome your patience and do not forget being grateful for the blessings that you receive. God has left no room for any excuse for you by sending clear reasons and divine Books.”
