Al-Hasan (may Allah have mercy on him) narrates: I heard Sayyiduna Jundub (may Allah be pleased with him) narrating from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "How will you be with regard to groups whose leader will enter Paradise while their followers go to the Fire?" The Companions said: "O Messenger of Allah, even if they do the same deeds as they (the leaders) did?" He (peace and blessings be upon him) said: "Yes, even if they do the same deeds as theirs." They said: "O Messenger of Allah, how will that be?" He (peace and blessings be upon him) said: "The leaders will enter Paradise because of their precedence and earlier good that was decreed for them, while the followers will go to the Fire because of the new things (and innovations) that they invented later."
No one narrated this hadith from al-Hasan (may Allah have mercy on him) except al-Salt bin Mihran, while Ali bin Nasr is alone in transmitting it.
