Ruling on milk banks

In America there are banks known as milk banks, which buy milk from nursing mothers then sell it to women who need to give it to their children but their own milk is lacking, or they are sick or are too busy working, etc. What is the ruling on buying milk from these banks?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, who replied as follows:

This is haraam. It is not permissible to establish this kind of bank, because this is human milk, and the milk from different mothers will be mixed, so that no one will know who is the mother. In Islam, drinking the milk of a woman creates the same relationship as does a close tie by blood (i.e., it has an effect on whom one may and may not marry, etc.). If the milk is of any kind other than human, then there is nothing wrong with milk banks.

And Allâh knows best.
