Volume 2, Book 13, Number 36:
Narrated As-Saib bin Yazid:
The person who increased the number of Adhans for the Jumua prayers to three was Uthman bin
Affan and it was when the number of the (Muslim) people of Medina had increased. In the life-time
of the Prophet I there was only one Muadh-dhin and the Adhan used to be pronounced only after
the Imam had taken his seat (i.e. on the pulpit).
