What is the ruling on praying in a dark room, and is it true that praying in the dark repels angels?

There is no objection to praying in the dark. Authentic hadiths have been reported indicating that the Prophet, peace and blessings be upon him, used to pray in the dark, as 'Aisha, may Allah be pleased with her, narrated that houses at that time did not have lamps. None of the scholars disliked praying in the dark; in fact, it may be more conducive to concentration. As for the saying that angels do not attend dark places, it is false and has no basis.
