lhsan is perfection in performing one's obligations. It is worshipping Allah as though you see Him, but if you are unable to imagine Him, you should remember that He ~ sees you. When a sinner is removed from the state of lhsan , he/she is deprived of receiving the Reward(s) of Allah ~' which are given to those who excel in fulfilling their religious duties. When lhsan is related to the heart, it prevents it from committing sins; because a person who worships Allah ~ ' with perfection, is one whose heart is filled with love, hope , fear and remembrance of Allah ~ - He worships Allah ~ as though he sees Him, and so he is prevented from disobeying Him. Therefore, when a person is removed from the state of lhsan , he/she is left among his/her own private company to try to enjoy life. If Allah ~ wants good for him/her, He ~ assigns him/her at the circle of the believers; but if he/she disobeys Allah ~ and indulges in sins, Allah ~ removes him/her from the state of Iman (good faith), as was said by the Prophet ~ : "A fornicator is not a believer at the time of committing fornication. The one who drinks wine is not a believer at the time of drinking wine. A thief is not a believer at the time of thieving ... " 1 Therefore, avoid committing sins , whatever their nature, and take the chance to repent, while it is still possible for you to do so .
