Exquisite harmony, winsome melodies and a uniformly devout message in honour of the Islamic faith have made Raihan one of the most influential—and commercially successful—nasheed groups in the world. Initially controversial in their homeland of Malaysia for daring to set Koranic verses and spiritual guidance to popular music, Raihan's pious purpose and gorgeous tones have led them to being embraced by Muslim communities across the globe. The group's arrangements, four-part harmonies over smoothly flowing tambourine and tabla rhythms, are simultaneously meditative and spiritually inspirational.
