The Kitáb-i-Aqdas - The Most Holy Book
Index term: Hand(s)
k34.
The kissing of hands hath been forbidden in the Book. This practice is prohibited by God, the Lord of glory and command. To none is it permitted to seek absolution from another soul; let repentance be between yourselves and God. He, verily, is the Pardoner, the Bounteous, the Gracious, the One Who absolveth the repentant.
k46.
Whoso wisheth to make use of vessels of silver and gold is at liberty to do so. Take heed lest, when partaking of food, ye plunge your hands into the contents of bowls and platters. Adopt ye such usages as are most in keeping with refinement. He, verily, desireth to see in you the manners of the inmates of Paradise in His mighty and most sublime Kingdom. Hold ye fast unto refinement under all conditions, that your eyes may be preserved from beholding what is repugnant both to your own selves and to the dwellers of Paradise. Should anyone depart therefrom, his deed shall at that moment be rendered vain; yet should he have good reason, God will excuse him. He, in truth, is the Gracious, the Most Bountiful.

The kissing of hands hath been forbidden in the Book.
In a number of earlier religious Dispensations and in certain cultures the kissing of the hand of a religious figure or of a prominent person was expected as a mark of reverence and deference to such persons and as a token of submission to their authority. Bahá'u'lláh prohibits the kissing of hands and, in His Tablets, He also condemns such practices as prostrating oneself before another person and other forms of behaviour that abase one individual in relation to another. (See note 58.)
n73.
Take heed lest, when partaking of food, ye plunge your hands into the contents of bowls and platters.
This prohibition was defined by Shoghi Effendi as "plunging one's hand in food". In many parts of the world it has been customary to eat with the hands from a communal bowl.
