5-36 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Sa’ed ibn Abdullah quoted Ahmad ibn Muhammad ibn Isa, on the authority of Al-Hussein ibn Sa’id, on the authority of Hammad ibn Isa, on the authority of Hurayz, on the authority of Zurarah that Aba Abdullah as-Sadiq (MGB) said, “Do not say your prayer again except for five issues: purity; proper time; the proper direction (of the Qibla) to which you turn to pray; the bowing down; and the prostration.” Then he (MGB) added, “Reciting, the Tashahhud and the Takbir (saying God is Great) are due to the Prophet’s tradition. What is done based on the Prophet’s tradition is not contradictory to God’s ordinance.”
