Prayer (Kitab Al-Salat)

Dawud :: Book 2 : Hadith 654

Narrated AbuHurayrah:

The Prophet (peace_be_upon_him) said: When any of you prays, he should not place his sandals on his right side or on his left so as to be on the right side of someone else, unless no one is at his left, but should place them between his feet.
