If it is said, “Perhaps there is a barrier between them,” the reply is:
The presumption is that there is none. Moreover, this is mentioned to demonstrate His power to bring forth something wholesome for consumption from between two unwholesome substances. This demonstration is complete only if there is no barrier. With a barrier in place, however, the outcome would be evident from the perfection of His creation—glory be to Him.
The same applies to His words, “pure.” Such purity must coexist with that which gives cause to drink. In short, milk emerging from between digested matter and blood closely resembles semen emerging through the urinary passage.
Those who consider the rennet and milk of an animal that died without lawful slaughter to be pure have followed this line of reasoning: the contents were pure, and impurity arose only in their container. They therefore say, “Internal contact is not outward contact.” Those who regard these as impure distinguish them from semen on the grounds that semen also separates from the impure substance internally. Milk, by contrast, cannot be separated from the dead animal until the udder is exposed; at that point, it comes within the category of things susceptible to impurity.
“Allah speaks the truth, and He guides to the right way.”
Praise be to Allah, and peace be upon His servants whom He has chosen. This is what has occurred to me at this time. There is neither power nor strength except through Allah, the Most High, the Magnificent.
