Kitab-i-Aqdas/Elder76

He gave a command regarding the Most Great Cleansing, and the washing of things that were soiled by dirt, how solidified filth (is removed), and other matters. Fear God and be of the purified.

The prayers of the one who is seen with filth on his clothes do not ascend to God and the exalted Beings avoid him.

Use rose water, then pure perfume. This is what God, who has no beginning, loved from the beginning. This is in order that there might be diffused from you the odour that your Lord, the Mighty and the Wise, desired.
