The ruling on eating fruits that grew in animal manure

Question:
The Shaykh’s question: Is it permissible to eat the fruits of date palms, or anything that bears fruit, if the soil has been fertilized with animal manure?

Answer:
Or regarding the manure of pure animals: the manure of camels, cows, sheep, and animals whose meat is eaten is pure, and there is no harm in that. As for what is named impure, such as dung and the excrement of donkeys and other things classified as impurities, this is the point of disagreement. The point of disagreement is that the school of thought (madhhab) holds that it is not eaten because it was nourished by impurity, while the second opinion holds that it is eaten because it has undergone transformation, as the impurity has transformed and no longer remains.
And they say that a thing becomes pure through transformation; this is according to the second opinion. But the school of thought holds that impurity does not become pure through transformation, so it is not eaten. Therefore, the Prophet (peace and blessings be upon him) prohibited the meat of al-jalalah, which is the cow or sheep that eats dung. If it is slaughtered, its meat is not eaten immediately until it is confined and fed pure food for three days until the impurity is removed. If it is slaughtered immediately and the impurity is in it and in its stomach, the Prophet (peace and blessings be upon him) prohibited the meat of al-jalalah and its milk; its milk is not drunk until it is confined and fed pure food. So the conclusion is that what is named impure is avoided, while what is named pure, such as the excrement of animals whose meat is eaten, is a good thing.
