Umar ibn Abd al-Rahman al-Attas (d. 1072/1652) was a great Sufi and scholar of the Bâ Alawi sada family whose lineage reaches Ali; he is known by the epithet "Qutb al-Anfas" and is the founder of the Attas branch of the Bâ Alawi. He studied under masters of his age such as Husayn ibn Abu Bakr ibn Salim and was regarded as a spiritual leader in Hadramaut. His most famous work is the Ratib al-Attas, a litany of remembrance and supplication drawn from Quran and hadith, still widely recited today. He died in the town of Huraydah, where he spent his final years, and was buried there.
