The story of Aisha (may Allah be pleased with her) with Mu'adhah bint 'Abd Allah regarding the making up of fasting by a menstruating woman, but not prayer.

The Shaykh : The mother of the believers, Aisha (may Allah be pleased with her), was asked: "Why does a menstruating woman make up her fast but not her prayer?" A woman who was making up her fast but not her prayer asked her, and she said: Her answer is based on the wisdom that we know that the fact that Allah commands a menstruating woman to make up her fast but not her prayer is that this is the wisdom. It is merely the command of Allah and His Messenger, and it is wisdom, O my brothers. Listen to the saying of Allah the Exalted: complete As long as Allah has commanded this, it is wisdom; as long as He has prohibited this, it is wisdom.
