Abu al-Najib Abd al-Qadir Suhrawardi (1097–1168) was a Sunni Persian Sufi who was born in Sohrevard, near Zanjan, and founded the Suhrawardiyya Sufi order. He studied Islamic law in Baghdad, then set up a retreat by the river Tigris, where he gathered disciples, which eventually came to be the Sufi order of Suhrawardiyya. His paternal nephew Shahab al-Din Abu Hafs Umar Suhrawardi expanded the order. His name is also sometimes transcribed as Diya al-din Abu 'n-Najib as-Suhrawardi.
