And the revelation that was delivered unto Mohammed peace and blessings be upon him, along was the gift of the Zeal of purities', was given as a humble remembrance, a deliverance of teachings', and this is revelational evidance unto mankind, and this Zeal of purities' was taught unto them, and from the highest revelation teacher meaning Mohammed peace and blessings be upon him, came teachers and imams' who followed directly thereafter, and therein, they learnt the deeper values of establishing the righteous prayers'.
