Hazrat Abu Hurairah (may Allah be pleased with him) narrated that we were sitting with the Messenger of Allah (peace and blessings of Allah be upon him) when these verses of Surah Al-Jumu'ah were revealed: "And (He has sent him) to others among them who have not yet joined them" . Hazrat Abu Hurairah (may Allah be pleased with him) says, I asked, "O Messenger of Allah! Who are these others?" The Messenger of Allah (peace and blessings of Allah be upon him) did not reply. I repeated the same question three times. Salman Al-Farsi (may Allah be pleased with him) was also present in the gathering. The Messenger of Allah (peace and blessings of Allah be upon him) placed his hand on him and said, "If faith were at the Pleiades, even then some men from these people (i.e., the people of Persia) would attain it," or he said, "A man from these people would attain it."

Abdullah bin Umar (may Allah be pleased with them) narrated that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: The example of people is like that of camels; out of a hundred camels, you will hardly find one fit for riding.
