Is this narration authentic?
عن كعب بن عجرة قال: خرج علينا رسول الله صلى الله عليه وسلم ونحن تسعة فقال: إنه ستكون بعدي أمراء من صدقهم بكذبهم، وأعانهم على ظلمهم، فليس مني ولست منه، وليس بوارد علي الحوض، ومن لم يصدقهم بكذبهم، ولم يعنهم على ظلمهم، فهو مني وأنا منه، وهو وارد علي الحوض
Yes, this Hadith is authentic.
Imam Nasai (rahimahullah) has recorded this version of the Hadith.
(Sunan Nasai; Al Mujtaba, Hadith: 4207)
Imams Tirmidhi and Ibn Hibban (rahimahumallah) have recorded the Hadith with slight variation in the wording and have authenticated the Hadith. See here.
Sayyiduna Ka’b ibn ‘Ujrah (radiyallahu ‘anhu) reports, Once Rasulullah (sallallahu ‘alayhi wa sallam) came out to us and and there were nine of us. He said: “Certainly, [tyrannical] rulers will come after me, whoever affirms their lies and supports their oppression is not from me and I am not from him, he will not drink from the pond [of Kawthar]. As for those who do not affirm their lies and do not support their oppression then he is from me and I am from him and he will drink from the pond [of Kawthar].”
And Allah Ta’ala Knows best.
