English Translation
Jubayr ibn Mut'im came to Ibn Umar and said: 'O Abu Abd al-Rahman, what did the Commander of the Faithful Umar say about the imam leading the people?' Ibn Umar said: Umar said: The Messenger of Allah (peace be upon him) said: 'The imam suffices for those behind him. If the imam makes a mistake, then he must perform two prostrations of forgetfulness, and those behind him must prostrate with him. And if someone behind him makes a mistake, he does not have to prostrate, for the imam suffices him.' Kharijah ibn Mus'ab narrated it from Abu al-Husayn al-Madini from Salim ibn Abdullah from his father from Umar from the Prophet (peace be upon him) with a similar meaning. Abu al-Husayn is unknown and al-Hakam ibn Abdullah is weak. And Allah knows best.
