SHAHIH BUKHARI CHAPTER NO.1 :THE BOOK OF REVELATION(HADITH 2)

HADITH NO.2
Narrated 'Aisha: (the mother of the faithful believers) Al-Harith bin Hisham asked Allah's Apostle O Allah's Apostle! How is the delightful Inspiration revealed to you? Allah's Apostle replied, Sometimes it is (revealed) like the ringing of a bell, this form of Inspiration is the hardest of all and then this state passes off after I have grasped what is inspired. Sometimes the Angel(farishtay) comes in the form of a man and talks to me and I grasp whatever he says. 'Aisha radhiallahu talah anhu' added: Verily I saw the Prophet muhammad s.w.t  being inspired delightfully on a very cold day and noticed the sweat release from his forehead {as the Inspiration was over}.
