What can be known only through reason includes our knowledge that there must be a being without beginning, since, if everything had come into existence, it would have come into existence without a cause. This knowledge precedes the coming of the Messenger and therefore does not require a messenger. Indeed, an example of this is our knowledge that the miracle of the Messenger of Allah, may Allah bless him and grant him peace, establishes his truthfulness.
What is known solely through instruction from the infallible Prophet includes our knowledge of the prescribed quantities of obligatory acts of worship, and matters pertaining to the Hereafter, such as Paradise, Hell, punishment in the grave, the Reckoning, the Balance, and other matters.
