Sunan Ibn Majah, Chapter: The Chapters of Purification and its Sunnah

that Muadh bin Jabal used to narrate something that the Companions of the Messenger of Allah (saw) had not heard, and he used to keep quiet about what they had heard. News of this report reached Abdullah bin Amr, and he said: "By Allah, I never heard the Messenger of Allah (saw) say this, and Muadh will put you into difficulty with regard to relieving yourself." News of that reached Muadh, so he met with him (Abdullah). Muadh said: "O Abdullah! Denying a Hadith from the Messenger of Allah is hypocrisy, and its sin is upon the one who said it (if it is not true). I did indeed hear the Messenger of Allah (saw) say: 'Beware of the three things which provoke curses: Relieving oneself in watering places, in places of shade and in the middle of the street.'" (Daif)
