Mukhtasar Bukhari

Narrated Abu Huraira (may Allah be pleased with him): (One day) we were sitting with the Prophet (peace and blessings of Allah be upon him) when Surah Al-Jumu'ah was revealed. When this verse was revealed: "And (He will raise this Messenger) among others who have not yet joined them..." I said, "O Messenger of Allah! Who are these people?" The Prophet (peace and blessings of Allah be upon him) did not answer me, until I asked three times. Among us was Salman Al-Farsi (may Allah be pleased with him). The Messenger of Allah (peace and blessings of Allah be upon him) placed his blessed hand on his head and said: "If faith were at the Pleiades (a distant star), even then a man or some men from among these (the people of Persia) would attain it."
