Gabru was born in Balochistan, Afghanistan in the 13th century. Shah Gabru met Shah Jalal during his meeting with Nizamuddin Auliya and decided to accompany him in his expedition towards the Indian subcontinent. In 1303, he took part in the final battle of the Conquest of Sylhet under Shah Jalal's leadership against Raja Gour Govinda. Following the victory, Shah Jalal ordered a small number of his companions to migrate to what is now known as Osmani Nagar. Gabru is noted to be a part of a collective known as the Panch Pir. He set up a hujra south of Banaiya Haor in a Hindu village. Many Hindu families embraced Islam due to his efforts and Gabru eventually married into one of the families. The elders of the family lovingly called him "Gabru" following the marriage; which led to him being more popularly known as Shah Gabru. The village was named after him as Gabhurteki.
