Imam-e-Rabbani Hazrat Mujaddid Alif Sa’ani Sheikh Ahmad Sirhindi (1564–1624) was an Indian Islamic Scholor from Punjab, a Hanafi jurist, and a prominent member of the Naqshbandi Sufi order. He is described as Mujaddid Alf  Thani, meaning the “reviver of the second millennium”, for his work in rejuvenating Islam and opposing the heterodoxies prevalent in the time of Moghal Emperor Akbar He is said to have had considerable and longlasting influence in India and to have given Indian Islam the stamp it bears today.

Many of the Naqshbandi suborders today, such as the Mujaddid,Khalidi Saifi,Taheri,Qasimya and Haqqani sub-orders, trace their spiritual lineage through Sirhindi, often referring to themselves as “Naqshbandī-Mujaddidī”.

Sirhindi’s shrine, known as Raoza Shareef is located in Sirhind, India.
