Hazrat Khwaja Nizamuddin Auliya (1238 - 3 April 1325) (حضرت خواجة نظام الدّین اولیا), also known as Hazrat Nizamuddin, was a famous Sufi saint of the Chishti Order in South Asia, an order that believed in respect for religious traditions and renunciation of worldly powers. He believed that pious action should be favored over religious worship.
He had a profound understanding of Akhlaq (Ethics) and believed that
mutual respect was necessary between devotional traditions. In this
vein, he advocated sulh e-kull, which means absolute peace amongst
devotional traditions, as well as langar, which is sharing food as
members of God's community.
