The great masters of the Naqshbandi Mujaddidi tariqah have not only blessed and authorized men to become masters of spirituality, they also taught this noble path to women, and often some of them were appointed as deputies, charged to teach the sacred path to women (and rarely, to men as well). Here are a few examples from authentic biographical sources.
Hazrat Bībī Daulat
She was authorized to teach the Naqshbandi tariqah to women by the great master Hazrat Khwājā Bāqī Billāh quddisa sirruh (971-1012 AH). [Zubdat al-Maqāmāt]
Hazrat Ajībā Khānum
She was wife of the great Islamic scholar and Sufi master of the Naqshbandi Order Hazrat Qādī Sanā-Allāh Pānīpatī. He is author of multiple books including Tafsīr al-Mazharī.
She was authorized by her shaykh Hazrat Mirzā Mazhar Jān-e-Jānān quddisa sirruh (1111-1195 AH) to teach the Naqshbandi Sufi method to the women seekers. Her husband was one of the major deputies of Mirzā Mazhar, as was her son Maulānā Ahmad-Allāh.
She had progressed to the higher stages of wilāyah (sainthood) such as Fanā (annihilation) and Baqā (permanence). Her shaykh Mirzā Mazhar wrote in a letter to her:
If women have the wish, and they ask for Tawajjuh from you, then it is permitted by me. It is highly hoped from the Masters [of the Naqshbandi tariqah] that it will be effective.
[Maqāmāt-i Mazharī, by Shāh Ghulām Alī Dehlavī]
Hazrat Bībī Sāhibā (d. 1218 AH)
Hazrat Shāh SafiyAllāh Sirhindī (1156-1212 AH) quddisa sirruh was one of the greatest shaykhs of the Mujaddidi tariqah among the descendants of Imam Rabbani Shaykh Ahmed Sirhindi raziyAllahu anhu. He is known to be a Qayyūm of this tariqah, the highest post of sainthood in the Mujaddidi path. He authorized his niece, who was often called Bībī Sāhibā, to teach the Naqshbandi path to women as well as men. He also wrote a khilāfat-nāmā (a certificate of authorization in tarīqāh) for her, and appointed her as his deputy in the Naqshbandi-Mujaddidi Sufi path. In that certificate, he also mentioned that she had reached the highest stages of wilāyah (sainthood) such as Wilāyat al-Kubrā (the major sainthood), Kamālāt al-Risālah (excellences of prophetship) and others, which are very rare and exalted spiritual stages, only taught in the Mujaddidi way.
She was the mother of Khwājā Fazl-Allāh Naqshbandī, author of Umdat al-Maqāmāt. Her father was Sayyid Atā-Allāh Shāh Bukhārī. She passed away in 1218 AH.
