When we were sitting with the Prophet sura al-Jum u'a[1] came down. Then when the words "and others of them who have not yet joined them"[2] came down, the people asked God's messenger who they were. Salman al-Farisi was among us, and placing his hand on Salman the Prophet said, "If faith were in the Pleiades some of these men would attain it." 1. Quran; 622. Verse 3(Bukhari and Muslim.)
