question #1 Sahih Muslim 666, Book 5, Hadith 354 : What is the significance of purifying oneself before going to the mosque for obligatory prayers?

The Messenger of Allah (may peace be’ upon him) said: He who purified himself in his house, and then he walked to one of the houses of Allah for the sake of performing a Fard (obligatory act) out of the Fara’id (obligatory acts) of Allah, both his steps (would be significant) as one of them would obliterate his sin and the second one would raise his status.
