Sunan Ibn Majah, 169

Rapporté par Abu Salamah : J’ai demandé à Abu Sa’eed Khudri : « As-tu entendu le Messager d’Allah ﷺ dire quelque chose à propos des Haruriyyah (une secte des Khawarij) ? » Il a répondu : « J’ai entendu parler d’un peuple qui semblait très pieux : “Chacun de vous trouverait sa propre prière et son jeûne insignifiants comparés aux leurs. Mais ils passeront à travers l’islam comme une flèche traverse sa cible. Ensuite, l’archer ramasse sa flèche, regarde la pointe et ne voit rien, regarde la hampe et ne voit rien, regarde la partie attachée à la pointe, puis regarde la plume et n’est même pas sûr d’y voir quoi que ce soit.” »

It was narrated that Abu Salamah said:"I said to Abu Sa'eed Khudri: 'Did you hear the Messenger of Allah mention anything about the Haruriyyah (a sect of Khawarij)?' He said: 'I heard him mention a people who would appear to be devoted worshippers: "Such that anyone of you would regard his own prayer and fasting as insignificant when compared to theirs. But they will pass through Islam like an arrow passing through its target, then he (the archer) picks up his arrow and looks at its iron head but does not see anything, then he looks at the shaft and does not see anything, then he looks at the band: that which is wrapped around the iron head where it is connected to the shaft, then he looks at the feather and is not sure whether he sees anything or not
