Waliuddin Abu Abdullah Mahmud Tabrizi, Selections from Muḥammadan Traditions…
“ In Islám the Traditions are used both in the formation of canon law and also in the exegesis of the Qurʾán; whilst not a little of what we know of the life and character of Muḥammad is derived from the same source. As every word and act of the Prophet is for the Muslim a divine rule of faith and practice, the influence of the Traditions on the lives of millions, all over the world, is difficult to over-estimate. A Tradition is technically divided by Muslim theologians into two parts. There is first, the isnád, the support or authority on which the Tradition rests. ”
