Jalam b. Shayban About the end of the 3rd/9th century, even
before the Fatimid Caliphate was established on the North

learned Qadi an-Nu'man (d. 363/ .974)., Chief Qadi of the
Fatimid Caliph ai-Mu'izz (d. 365/976), who states that in
270/883 the Yamani Da'i Abu I-Qasim b. Hawshab Mansur al-Yaman
sent his nephew al-Haytham as da'i (missionary) to Sind and the
Da'wa (mission) spread to Hind'.
