Sweet Breath In Prayer

If thou hast not a sweet breath in prayer, go and beg a prayer from the pure (in heart).

He (God) said, “O Moses, beseech Me for protection with a mouth thou hast not sinned withal.”
Moses said, “I have not such a mouth.”
God said, “Call unto Me by the mouth of others.” When didst thou sin by the mouth of others?
Invoke (God) by the mouth of others, crying, “O God!” Act in such wise that (their) mouths may pray for thee in the nights and days.
Ask pardon by a mouth with which thou hast committed no sin—and that will be the mouth of others
Or (else) make thine own mouth pure, make thy spirit alert and nimble.
