Index term: kissing, under 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.

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.
