Qi Jingyi (Chinese: 祁静一) (1656-1719), also known as Hilal al-Din, was a Chinese Sufi master, instrumental in the spread of the Qadiriyyah school among Chinese Muslims. He was known among his followers as Qi Daozu (祁道祖), i.e. Grand Master Qi.
According to Qi Jingyi's followers, the 16-year-old Qi Jingyi met the revered master Afaq Khwaja in Xining in 1672, and asked him to become his teacher. Afaq Khwaja supposedly said in response: "I am not your teacher; my ancient teaching is not to be passed on to you; your teacher has already crossed the Eastern Sea and arrived in the Eastern land. You must therefore return home quickly, and you will become a famous teacher in your land."
