Haḍrat Sayyid Ṭāhā Hakkārī Jīlānī Naqshbandī Khālidī qaddas-Allāhu sirrahū was one of the superior deputies of Mawlānā Khālid Baghdādī. He was a true Sayyid and a descendant of Sayyid ʻAbdul-Qādir Jīlānī raḍiy-Allāhu ʻanhu.
His uncle Sayyid ʻAbdullāh Jīlānī Hakkārī was also a perfect deputy of Mawlānā Khālid, who introduced Sayyid Ṭāhā to his shaykh. When Mawlānā Khālid saw Sayyid Ṭāhā, he ordered him to visit the shrine of Shaykh ʻAbdul-Qādir Jīlānī (in Baghdad) to ask him permission to join the Naqshbandī Order. Sayyid Ṭāhā obeyed and went there, and saw Shaykh ʻAbdul-Qādir in a vision, who told him to become a disciple of Mawlānā Khālid. Thus he started his spiritual journey in the Naqshbandī Mujaddidī Path, although his ancestral Sufi Path was Qādrī.
He died in 1269 AH (1853) in Nehri. He appointed his brother Shaykh Sālih as his successor. Among his perfected deputies were the following:
- Sayyid Muhammad Ṣālih, brother of Sayyid Ṭāhā
- Sayyid Ṣibghatullāh Arwāsī
- Sayyid Fahīm
