The venerable Makhdūm Abul-Qāsim Thattvī Naqshbandī Mujaddidī was one of the illustrated saints and Sufi masters of the Naqshbandī Path in Sindh during the early eighteenth century.
He was a murīd of Makhdūm Ādam Thattvī and a deputy of Khwāja Saifuddīn Fārūqī Sirhindī (d.1096 AH).
He was born in Thatta, then a city of knowledge, in Southern Sindh (Pakistan). Initially he was initiated in the Sufi Path by Makhdūm Ādam Thattvī, a deputy of Khwāja Muhammad Maʻsūm Sirhindī (d.1079 AH). When his shaykh saw his aptitude and talent, he guided him to go to Sirhind, where he met Khwāja Saifuddīn Sirhindī. There he competed the spiritual journey and was awarded deputyship.
When he returned to Thatta, he soon became popular and seekers flocked to him from far and wide. In Sindh, other Sufi Paths were more popular such as Qādrī and Suhrawardī. Makhdūm Abul-Qāsim made the Naqshbandī Path very popular in Sindh for the first time.
His personal room, where he slept and worshiped, was known as the Chamber of Presence. One day it so happened that while he was alone in the room, one of his disciples heard two persons talking in the room, one of whom he recognized as the Shaykh. The next day, the disciple asked him about this. He replied that I was talking to the Holy Prophet sallAllāhu ʻalayhi waSallam.
Hundreds of people used to stay at his dervish convent, although there was no apparent source of income for the convent. Whenever the servants asked him for money, he would raise his empty hand in blank air and gold coins would appear in his hands that he would give to the servants.
He passed away on 10 Shaʻbān 1138 (1726) and was buried in the famous cemetery of Thatta called Maklī.
