In accordance with the tradition of the scholars of Deoband and recognising the importance of tasawwuf, Usmani's bay'ah was accepted by Abdul Hayy Arifi and Maseehullah Khan.

He currently teaches Sahih al-Bukhari, fiqh, and Islamic economics at Darul Uloom Karachi and is known for his Islahi Khutbat. He was a key member of a team of scholars which helped declare Ahmadis (Qadianis), as non-Muslims by Pakistan's National Assembly during the era of former Pakistani president, Zulfikar Ali Bhutto, in the 1970s. During the presidency of General Zia ul Haq, he was instrumental in drafting laws pertaining to Hudood, Qisas, and Dayiat. He strongly opposed the Women's Protection Bill. According to him, it was designed to distract attention from issues such as flaws in the law enforcement system.
