In one narration the words are: "I have been commanded to fight the 'Nakithin' (the covenant-breakers)." After this the narrator mentioned the hadith as before.
Al-Bazzar recorded it, and al-Tabarani recorded it in al-Mu'jam al-Awsat; the narrators of one of al-Bazzar's two chains are the narrators of the Sahih, except al-Rabi' bin Sa'id, and Ibn Hibban declared him thiqah (trustworthy).
