you shall never stray...
you shall never stray," thus clearly stating that such writing would bring them security against straying; so, how can it be a reason for dissension just because the hypocrites might cast doubts about its authenticity? Had he [‘Umar] feared such hypocrites and their casting doubts about the authenticity of what the Prophet wished to write, why did he then plant the seed of such doubts himself when he opposed and objected and even said that the Prophet was delirious?
As regarding their interpretation of verses cited in support of ‘Umar's statement: "The Book of Allah suffices us," such as the verse: "We have left nothing unexplained in the Book (Qur'an, 6:38)," and "Today have I completed for you your religion (Qur'an, 5:4), " it is erroneous, for neither verse suggests a security against misguidance, nor do both verses guarantee guidance for people; so, how can relying on these verses justify abandoning the implementation of the texts whose writing the Prophet wished to record?
Had the presence of the dear Qur'an been to bring security against misguidance, then neither misguidance nor dissension, the removal of which is as hopeless as can be, would have ever taken place.[^1] In their final argument, they say that ‘Umar did not understand the tradition to imply that such writing would be a cause for protecting each and every member of his nation from misguidance; and that rather he understood that it would, after its writing, safeguard them against erring in their consensus.
They claim that ‘Umar, may Allah be pleased with him, knew that the error in their consensus would never occur, albeit if such writing had taken place or not, and that for this reason he opposed its writing thus. Besides what you have said, we may add that ‘Umar did not lack such a degree of understanding, and he was not blind to the implication of the tradition which became obvious to all people.
Urban residents as well as bedouins understood the intention of the Prophet (pbuh) that it would be a complete prescription for the protection of every individual against misguidance... only had it been written. This is the meaning which anyone can comprehend of this tradition.
