Note 17 — Chapter IX · THE SPREAD OF ISLAM IN INDIA.
Reading edition
The descendants of Sayyid Ajall played a great part in the establishing of Islam in China; it was his grandson who in 1335 obtained from the emperor the recognition of Islam as the “True and Pure Religion”—a name which it has kept to the present day,—and another descendant of Sayyid Ajall was authorised by the emperor in 1420 to build mosques in the capitals, Si-ngan-fu and Nan-kin.17
