"The whole earth has been made a mosque and [pure for me." - (Bukhari, )
He (Abud Darda) reported God's messenger as saying, "Is any of you capable of reciting a third of the Qur'an in a night?" On being asked how they could recite a third of the Qur'an he replied, " 'Say, He is God, One' is equivalent to a third of the Qur'an." Muslim transmitted it, and Bukhari transmitted it from Abu Sa'id.
