Hazrat Syed Abdullah Shah Qadri(R.A) (Urdu: سید عبداللہ شاہ قادری) popularly known as Bulleh Shah (R.A) (بلھے شاہ ) was a Mughal-era Punjabi Islamic philosopher and Sufi poet. His first spiritual teacher was hazrat Shah Inayat Qadiri(R.A), a famous Sufi murshid of Lahore.
Hazrat Bulleh Shah(R.A) lived after the Pashto Sufi poet Rahman Baba(R.A) (1632–1706 A.D) and lived in the same period as Sindhi Sufi poet Shah Abdul Latif Bhittai (RA) (1689–1752A.D). His lifespan also overlapped with the Punjabi poet Waris Shah (1722–1798 A.D), of "Heer Ranjha" fame, and the Sindhi Sufi poet Abdul Wahab(R.A) (1739–1829A.D), better known by his pen name Sachal Sarmast(R.A).
Hazrat Bulleh Shah(R.A) practised the Sufi tradition of Punjabi poetry established by poets like Hazrat Shah Hussain Qadri (R.A)(1538–1599 A.D), Hazrat Sultan Bahu(R.A) (1629–1691A.D), and Hazrat Shah Sharaf (R.A) (1640–1724 A.D).
The verse form Bulleh Shah primarily employed is the Kafi, popular in Punjabi and Sindhi poetry.
Many people have put his Kafis to music, from humble street-singers to renowned Sufi singers.
