Punishment of Disbelievers at War with Allah and His Apostle
Bukhari :: Book 8 :: Volume 82 :: Hadith 828
Narrated Aisha:
Abu Bakr came to towards me and struck me violently with his fist and said, "You have detained the people because of your necklace." But I remained motionless as if I was dead lest I should awake Allah's Apostle although that hit was very painful.
