The question that made Shaykh Ibn Uthaymeen laugh

The questioner : The Shaykh’s daughter, this is a questioner asking, or rather a woman asking, and she says: What is the ruling on women swimming together in a closed pool exclusively for women, given that the women wear modest clothing?

The Shaykh : What is the benefit for a woman in swimming? It is strange. What is the exercise? I swear by Allah, I do not issue a ruling for her. Because this opens the door to evil. And women, as you know, are weak in religion and in thinking, and once the door is opened, it may not be possible to close it later.
