Is the ink that comes out of the marine cuttlefish ritually impure?

The questioner : There is a type of sea creature that, when it senses danger, releases a substance called ink. It is called the cuttlefish.

The Shaykh : It can be collected in a jar and put in the sheep. I am asking you. Can this ink be collected in a jar and used to fill a pen?

The questioner : It resembles ink and is called ink.

The Shaykh : It is permissible. We like it.

The questioner : Before it is seen.

The Shaykh : We have a rule: everything that comes out of an edible animal is pure. Do you understand? The urine of an edible animal is pure, the dung of an edible animal is pure, the vomit of an edible animal is pure. It is my opinion that this ink cannot be erased if we find it.

The questioner : Now. It is possible to this extent.

The Shaykh : Yes, it means if it is a lot of ink, that is.

The questioner : It releases this substance to protect itself so that it is not seen.

The Shaykh : It is very much, it covers it.
