never stand in that mosque* indeed the mosque** that has been founded on piety from the very first day deserves that you should stand in it in it are the people who wish to thoroughly cleanse themselves and allah loves the clean. 
لا تقم فيه أبدا لمسجد أسس على التقوى من أول يوم أحق أن تقوم فيه فيه رجال يحبون أن يتطهروا والله يحب المطهرين
