Your Fifth Question
Fifteen is accepted as the age of discretion. How did Allah the Most High’s Messenger (Upon whom be blessings and peace) worship before his prophetic mission?
The Answer: He used to worship in accordance with what remained of Abraham’s (Upon whom be peace) religion, which was still extant in Arabia though in very obscure form. But this was his own choice, to perform a good act, not because he was obliged or compelled in any way. This truth is lengthy, so let it remain at that for now.
