See, for instance, "The Lost Camel" in Idries Shah's collection World Tales. The author mentions that an ancient saying, "Faith is the lost camel of the Believer", has been said to allude to this tale. The same story is found in Tales of the Sun Or Folklore of Southern India by Mrs Howard Kingscote (Georgiana Kingscote) and Pandit Natêśa Sástrî, accessible here.
