Regarding milk mixed with other substances, when is prohibition established?
General Chapter
Al-Mughni
Book of Fosterage (Breastfeeding)
Primary text
Pure milk is that which has no admixture. Al-Kharqi makes no distinction, stating that whether it is mixed with food, drink, or anything else, the ruling is the same. Al-Shafi'i holds this view. The primary view maintains that if the milk remains apparent, it is considered as having been drunk, causing flesh growth and bone strengthening, thus establishing prohibition, similar to when milk is predominant. This applies when the characteristics of milk remain. If milk is poured into a large amount of water such that it does not change, prohibition is not established because this is neither mixed milk nor does it result in nourishment, flesh growth, or bone strengthening.

Abu Bakr, basing his view on the analogy of Ahmad's position, argues that prohibition is not established because it falls under the ruling of wujur (liquid passing the throat without swallowing). Ibn Hamid stated that if milk is predominant, prohibition is established; otherwise, it is not. This view is also held by Abu Thawr and Al-Muzani, based on the principle that the predominant substance governs the ruling. The school of opinion of the Ra'i scholars agree generally, adding that if fire has touched the milk to cook the food or change its character, it is not nursing.
