What is the ruling on the yeast that is put into flour in order to make bread?

The questioner : What is the ruling on the yeast that is put into flour... to make bread so that it becomes puffed up? And you have answered this in a previous session or sessions. He says: I borrowed a sum of money in a foreign currency from one of my companions and promised to repay him. Of course, we are referring to the question we mentioned regarding the ruling on yeast, where you said, may Allah bless you, that there is nothing wrong with it, that it is put into the flour, and that the ruling on intoxicants does not apply to it.

The Shaykh : Yes.
