Two Sufi saints originally from Shaam (Syria) who, during Hajj in Mecca, took bay'ah from Shah Kalimullah Jahanabadi and followed him to Delhi. They served as military commanders under Aurangzeb and, after the Deccan campaign, settled in Hyderabad to teach Islam; they died on the same day and were buried beside their Nampally residence ('Yousufain' = the two Yusufs). The Urdu poet Daagh Dehlvi is also interred here. Their death is dated 6 Dhu al-Hijja 1121 AH (1710). (Sources: Wikipedia 'Dargah Yousufain'; yousufain.org)
