ihsan is a very vast term.generally it is translated as every act that is known as "birr" but broadly speaking,ihsan means to do the things appropriate way in the light of Quran,hadith and sunnah.To do justice with your duties is ihsan as well.Ihsan also commonly means to do a good deed to someone when he needs that favour.
