Muwatta Imam Malik (Riwayat Yahya)

Imam Malik, may Allah have mercy on him, said: In our view, the ruling is that if a person steals goods from the market which the owners have kept secured in a container, mixed together with one another, and steals the equivalent of a quarter dinar, then his hand will be cut off, whether the owner is present there or not, whether it is night or day.
