Mishkat al-Masabih #387

Ubayy b. Ka‘b reported the Prophet as saying, “Ablution has a devil called al-Walahan, so guard against the confusion caused by water.” Tirmidhi and Ibn Majah transmitted it, and Tirmidhi said, “This is a gharib tradition whose isnad is not considered by traditionists to be strong, because we know of no one but Kharija who traced it to the Prophet, and in the opinion of our school he is not strong.”
