It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There will come people who will lead you in the prayers. If they pray them completely, the reward is for them and for you; and if they fall short, the burden of it is upon them, and for you (there is still reward)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Safwan bin Sulaym (may Allah have mercy on him) except Abu Ayyub; Abd al-Rahim bin Sulayman is alone in narrating it."
