salaam

I would like to inquire, how the steps of salaah and whudu came into being: from the start of whudu how the natural process to cleanse oneself and also the same for salaah - being in the state of it today. starting with Takbeer and ending with salaam.

I am not doubting it, more and more now that my Imaan is improving I find it important to understand why and how Islamic principals were laid down to the Ummah etc....
