Abu Ishaq Shami (ابو اسحاق شامی چشتی; died 940) was a Muslim scholar who is often regarded as the founder of the Sufi Chishti Order.^[2] He was the first in the Chishti lineage (silsila) to live in Chisht^[3] and to adopt the name "Chishti", so that, if the Chishti order itself dates back to him, it is one of the oldest recorded Sufi orders. His original name, Shami, implies he came from Syria (ash-Sham). He died in Damascus and lies buried on Mount Qasiyun, where Ibn Arabi was later buried.

Abu Ishaq Shami's teacher was Mumshad Al-Dinawari, whose own teacher was Abu Hubayra al-Basri, a disciple of Huzaifah Al-Mar'ashi who was in turn a disciple of Ibrahim ibn Adham (Abu Ben Adhem In the western tradition.) The Chishtiyyah silsila continued through Abu Ishaq Shami's disciple Abu Aḥmad Abdal Chishti.^[4] In South Asia Moinuddin Chishti, whose silsila goes back to Abu Ishaq Shami, was the founding father who brought Chishti teaching to the region. He remains the most revered saint of the Chishti order in India and Pakistan. ^[5]

Some of Abu Ishaq Shami's sayings are:

• “Starvation excels all in bliss.“
• “The worldly people are impure while the dervishes are pure in their souls. These two different natures cannot therefore mingle.”

• Sufism
