Dhai Qalandar
Dhai Qalandar is a group of Sufi Saints which includes three "Qalandar" namely Hazrat Lal Shahbaaz Qalandar, Hazrat Bu Ali Shah Qalandar and Hazrat Bibi Rabia Basri Qalandar.
Etymology
Dhai is an Urdu-Hindi term which means 2.5 (two and half). So the Hazrat Lal Shahbaz Qalandar and Hazrat Bu Ali Shah Qalandar are the two Qalandars whereas Hazrat Bibi Rabia Basri is regarded as the "adhi" Qalandar or half Qalandar.
