Ihsan is the highest status of religion Islam. Its definition that our beloved Prophet Muhammad peace be upon him described is: “To worship Allah as if you see Him, and if you do not see Him, He sees you.” The concept of Ihsan in Islam is also that a Muslim is a responsible person where he does things in a good manner. We can say that Ihsan means a Muhsen is sure that Allah is seeing him/her in everything he/she says or does in his life. So, a Muhsen does his best to say and do only what pleases Allah Almighty and conforms to His commands.
In Holy Quran, Allah Almighty says:
''Indeed, Allah commands justice, good conduct (Ihsan), and giving to relatives (and He) forbids immorality, bad conduct, and oppression. He admonishes you that perhaps you will be reminded'' (Surah an-Nahl, 90).
In short, by living according to the concept of Ihsan and by applying it to all that a Muslim does, he/she will be rewarded and drench with mercy and forgiveness from Allah Almighty
