The Messenger of Allah ﷺ forbade eating the meat and drinking the milk of animals that feed on filth.
حدثنا سويد بن سعيد حدثنا ابن أبي زائدة عن محمد بن إسحق عن ابن أبي نجيح عن مجاهد
نهى رسول الله ﷺ عن لحوم الجلالة وألبانها

Takhrij: Hadith 3785 [hasan]. Reported by Abu Dawud in the Book of Foods, chapter on the prohibition against eating jallalah animals and drinking their milk, from the hadith of Ibn Ishaq through this route. I did not find an explicit statement of his having heard it, nor of Ibn Abu Najeeh having heard from Mujahid. The hadith has corroborating reports, among them what Abu Dawud reported at hadith 3787 and elsewhere.
