مخلص
Mukhliṣ
The active participle of ikhlāṣ: a person who is sincere in devotion to God; the plural is mukhliṣūn.
What it means
Mukhliṣ is the person who acts with ikhlāṣ, sincerity, which means doing a deed purely for God. The Quran commands, “Worship God, making your religion sincere to Him” (39:2), and it describes those who call on God in distress as “sincere to Him in religion” (29:65). The word names the person who directs worship to God alone, with no show and no partner. The passive form, mukhlaṣ, means one chosen and purified by God. It is used of Joseph (12:24) and of prophets and servants whom Satan cannot lead astray (15:40). The 112th surah is called al-Ikhlāṣ, since it declares God’s oneness.
Often misunderstood as
It is sometimes read as a social virtue of honesty, when in the Quran it concerns directing worship to God alone.
