ANSWER:

From the feet to the prostration spot.

The prophet salla allahu alaihi wa sallam said that the earth was made for him a place of purity and prayer.

Therefore, the default is that all grounds are pure until proven otherwise. 

QUESTION: The spot of praying should be pure is a condition for the validity of prayer. My question is what is the extent that we should keep pure when we pray?From Our feet to the prostration spot or something else?

Prayer, Purity |
