Muwatta Imam Malik (Riwayat Yahya)

Imam Malik, may Allah have mercy on him, said that similarly, if a man steals from his wife’s property which is not in the house where they both live, but is kept in another house, or if a woman steals from her husband’s property which is not in the house where they both live, but is locked in another house, then the hand will be cut off.
