Ikhlas اخلاص, in its actually meaning, means to be pure from, and can be also used as the word sincerity.
In Quran we have Surah Ikhlas,in Which Allah introduces himself, as being pure of and unlike any of his creations.
وَلَمْ يَكُن لَّهُ كُفُوًا أَحَدٌ
And there is nothing comparable to Him
(112:4)
The definition of Ikhlas from a creation to creator perspective, is called Kholoos خلوص , which means, seeking to be pure or to be purely for the Creator in your thoughts and action, for the love of the Creator himself.
In English the closest term that may explain Ikhlas briefly is the word- Sincerity.
Quran Ayas:
قُلْ إِنِّي أُمِرْتُ أَنْ أَعْبُدَ اللَّهَ مُخْلِصًا لَّهُ الدِّينَ
Say, “I was commanded to serve God, devoting my religion exclusively/sincerely to Him. (39: 11)
قَالَ فَبِعِزَّتِكَ لَأُغْوِيَنَّهُمْ أَجْمَعِينَ -إِلَّا عِبَادَكَ مِنْهُمُ الْمُخْلَصِينَ
He(Satan) said, “By Your majesty, I will seduce them all.(38:82)
Except for your purely sincere servants among them(38:83)
Ikhlas is the beautifier of the worshipper.
The interesting thing about Ikhlas ( sincerity) is, It is not specific to believers . God mentions in the Quran that even those who attribute partners to Allah ( Moshrik), in times of extreme desperation seek only The one God with full sincerely:
فَإِذَا رَكِبُوا فِي الْفُلْكِ دَعَوُا اللَّهَ مُخْلِصِينَ لَهُ الدِّينَ فَلَمَّا نَجَّاهُمْ إِلَى الْبَرِّ إِذَا هُمْ يُشْرِكُونَ
When they embark on a vessel, they pray to God, devoting their faith to Him; but once He has delivered them safely to land, they attribute partners to Him.(29: 65)
Hadith:
Hadith Qudsi, God says: Sincerity is the secret of my secrets that I safekeep it in the mind of who I love.
