مفلح
Mufliḥ
A person who has succeeded in his or her commitment to Islam; the plural is muflihūn.
What it means
Muflih is the one who has succeeded or prospered, from the root f-l-ḥ, whose noun is falāḥ. The Quran uses it of the believers who have kept their commitment: “Those are on guidance from their Lord, and those are the successful (al-muflihūn)” (2:5). The twenty-third surah opens, “The believers have succeeded” (23:1). The root has a place in daily worship, because the call to prayer says ḥayya ʿalā al-falāḥ, “come to success”. The measure of success is lasting: it concerns the standing of a person before God in the next life, and not wealth or status.
Often misunderstood as
Rendering it as “prosperous” suggests worldly gain, while the Quran uses it for success in the sight of God.
