A woman who reached menstruation before the age of fifteen and did not pray until she reached fifteen

The questioner : All right, now, Umar, what do you say about a woman who reached puberty while still young, menstruated while young, and did not fast the month of Ramadan on the basis that fasting is not obligatory for her until she reaches fifteen years of age?

The Shaykh : There is a distinction here. She was in a village with scholars, and I ordered her to fast, because she was negligent.

The questioner : Yes.

The Shaykh : So she owes nothing. That is, the default is that we do not order her to make up the fasts until we know that she was negligent, because if she was negligent, she left off what was obligatory for her. So this is why we said: but if she was negligent in learning, that is a matter for consideration, so let her learn.
But if the ignorant person was negligent in learning and did not learn what is required of him, that is a matter for consideration, so let her learn. Does the meaning of "let her learn" mean that this is a matter for consideration, or does it mean "let her learn," i.e., search until you reach knowledge? Yes, it carries two meanings, but the more important one is this meaning: that "let her learn" means that since this matter is a subject for consideration, verify the issue until you reach knowledge in it and the matter becomes clear to you. And the Shaykh al-Islam (may Allah have mercy on him) investigated this issue in the first book of prayer in the book al-Ikhtiyarat. So whoever wants to refer to it, let him refer to it, for his words on it are beneficial.
