Prayer
Prayer is the miraj (union with, or annihilation in, the Divine Essence by means of continual upward progress) of the Faithful.
The Lord doth not regard a prayer in which the heart doth not accompany the body.
He whom prayer preventeth not from wrongdoing and evil, increaseth in naught save in remoteness from the Lord.
The key of Paradise is Prayer, and the key of prayer is ablution.
Say your prayers standing; but if you are not able, sitting; and if unable, on your sides.
