Among non-Muslims, the concept of the houri received wide publicity as "virgins" (most usually 72 in number for each shahid) promised as a reward to Muslim
shahids (martyrs), after their death. However, contrary to such reports, the
Quran states that all believers (not just martyrs, and nowhere either is it said it's just men) who go to Heaven shall be granted the company of more than one houri—explicitly mentioned in the plural, and the number 72 comes from a
hadith with a weak
chain of narrators (i.e. less than totally reliable), and not the Quran.
