Narrated 'Aishah: that Al-Harith bin Hisham asked the Prophet (ﷺ): 'How does the Revelation come to you?' The Messenger of Allah (ﷺ) said: 'Sometimes it comes to me like the ringing of a bell and that is the hardest upon me, and sometimes the angel will appear to me like a man, and he will speak to me such that I understand what he says.'" 'Aishah said: "I saw the Messenger of Allah (ﷺ) while the Revelation was descending upon him on an extremely cold day. Then it ceased and his forehead was flooded with sweat."
