(a) It is narrated from Nu'aym al-Mujmir: I was praying behind Abu Hurayrah (may Allah be pleased with him). He (may Allah be pleased with him) recited 'In the name of Allah, the Most Gracious, the Most Merciful' [Surah al-Fatihah: 1], then recited Surah al-Fatihah, and when he reached 'nor of those who are astray' [Surah al-Fatihah: 7] he said 'Amin', and the other people also said 'Amin'. Whenever he prostrated he said 'Allahu akbar' (Allah is the Greatest), and when he stood up from sitting he also said 'Allahu akbar'. When he concluded with the salam, he said: "By the One in whose Hand is my soul, I am the most similar of you all to the Messenger of Allah (peace and blessings be upon him) in prayer."
(b) In the narration of Ibn Abd al-Hakam, instead of the words 'I was behind Abu Hurayrah', the words are 'I prayed behind Abu Hurayrah'.
This is an authentic (sahih) chain, and it has supporting narrations (shawahid).
