Selling watered-down milk with the buyer informed
Question
Nowadays those who trade in milk sell milk after mixing water into it. Some buffalo owners supply it to shopkeepers already mixed with water, then the shopkeepers mix more water into it and sell it, so that the milk does not even keep its taste. If one says to the shopkeepers, “Brother, since you take a price of 5 and 6 per seer (a unit of weight, ≈ 0.93 kg), do not give milk mixed with water,” the reply comes: “We will give it only mixed with water; take it if you like, or don’t.
Answer
When they do not deceive but say, “We have mixed water into it,” then it is correct according to the Shari‘a.
