Linguistically Doers of good = Muxsiniinta = المحسنين
Muxsin is the one who practices isxaan=الإحسان
Ixsaan is to do xasanaat also to do better. In Technical sense It is as nabiga scw said to jibriil
قَالَ: أَنْ تَعْبُدَ اللَّهَ كَأَنَّك تَرَاهُ، فَإِنْ لَمْ تَكُنْ تَرَاهُ فَإِنَّهُ يَرَاك
He said: (it is) that you worship Allaah as if you see Him, for if you cant see Him then indeed He sees you.
And this is the isxaan of Ibraahim alKhaliil and the other prophets
