She said “The Messenger of Allah(ﷺ) would go out (from Madina) to these torrential streams. Once he intended to go out to the desert (for worshipping Allaah). He sent me a She-Camel from the Camels of sadaqah that was not used as a mount. He said to me “A’ishah be lenient, for leniency makes a thing decorated and when it is removed from a thing it makes it defective.
