Sheikh Umar bin Qulatayn (also spelled as Kulatein, Kulatayn, Qulatein) bin Mudhir was an Islamic scholar following the Sufi Order of Qadariyah. Coming from Barawa, he traces his lineage to Hadramaut in Yemen and belonged to the Nadhiri family. He moved to Zanzibar at a young age where he was appointed as the Khalifa of Qadariyah later on in his life.
Sheikh Umar Qulatayn was an Ashraaf who belonged to the Nadhiry Family of the Ba Alawi, the Ba Alawi or Sadah Ba ‘Alawi (Arabic: السادة آل باعلوي, al-sādatu al-bā’alawiy) are a group who are part of the Hadhrami Sayyid families in Hadramout, (Anne, 2003). They trace their lineage to Sayyid Ahmad al Muhajir, They are believed to be descendants of the Family of the Prophet Muhammad (Peace be upon him).
Sheikh Umar Qulatayn’s family migrated to Barawa at a time when many Ashraaf families since 1700 AD were migrating out of Hadhramout across the world, often to spread Islam. He got married in Barawa and settled there, until he decided to join his father in Zanzibar who use to frequent there for trade and business.
Upon moving to Zanzibar, he married again from the Shatiri family (Al-Shatiri) who are another group belonging to Ba Alawi. He stayed much of his life in Zanzibar where he continued working for his father, he pursued Islamic knowledge from a young age and it was in Zanzibar where he met Sheikh Uways ibn Muhammad Al Qadiri Al Barawi. Historical sources held that it was Sheikh Uways who gave him Ijaza to become the Khalifa of Qadariyah in Zanzibar.
