The answer to all of the above is a big resounding NO !

Surely the Prophet (Sal Allaahu Alaihi Wassallam) did not omit or forget anything in the deen! Surely he did not hide anything from mankind!

The Prophet (Sal Allaahu Alaihi Wassallam) said, “There is nothing that brings you closer to Jannah except that I have informed you about it and there is nothing that brings you closer to the fire of Hell except that I have warned you against it.”
