Sahih Bukhari Volume 6, Book 60, Hadith Number 189.

Narrated By Abu Said : Something was sent to the Prophet and he distributed it amongst four (men) and said, “I want to attract their hearts (to Islam thereby),” A man said (to the Prophet), “You have not done justice.” Thereupon the Prophet said, “There will emerge from the offspring of this (man) some people who will renounce the religion.”
