Dastgir (pronounced dɑʂt-ģir, ) from Persian, literally "Holder of the Hand") is a name common in South Asia and the Middle East. In Arabic, it is used as a first name and means 'helper' or 'supporter'. In Pashto and Persian, it means 'saint' or 'the saint of saints' and can be used as a title, a name, or an ethnic surname. The suffix zâda or zâdeh (Persian for son of) is sometimes added in the Persian and Pashto variations to denote "son or descendant of a saint".
It was popularly used to refer to one saint in particular from the region, Shaykh Abdul Qadir Gillani, founder of the Qadiri Sufi order. It is often said the term itself arose with him, since he had the title al-Gauth al Azam (the "Supreme Helper"), and the root of Dastgir literally denotes a helper or helping hand.
