Machine translationRead the Arabic original
Question:
Is fasting the three days evidence that they are the white days? And if that is not the case, what is the evidence for fasting the white days?
Answer:
Fasting three days is the original ruling. If he makes them the white days, that is better, by making them the thirteenth, fourteenth, and fifteenth days, when the moon is present throughout the night. They are called "white" because of the whiteness of their nights due to the moon. So if he fasts the three days on these days, it is better. And if he fasts them at the beginning of the month or at the end of it, there is no harm. Yes.
