Abu al-Ahwas narrates that Sayyiduna Abdullah (may Allah be pleased with him) said: "Women are something to be kept concealed. A woman goes out of her house while there is nothing wrong with her, and Satan urges her on and says: You will not pass by anyone without him admiring you. And a woman puts on her clothes, and she is asked: Where are you going? She says: To visit someone who is sick, to attend a funeral, or to pray in a mosque. Yet a woman has never worshipped her Lord with anything like worshipping Him in her house."
