It is narrated from Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) that Sayyiduna Harith bin Hisham (may Allah be pleased with him) asked the Prophet (peace and blessings be upon him): How does revelation come to you? The Prophet (peace and blessings be upon him) replied: "Sometimes it comes like the ringing of a bell, and that is very hard upon me. Then when it ceases, I remember what has been said. Sometimes the angel comes to me in the form of a man and speaks to me, and I remember what he says." Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her) says: When revelation would descend upon the Prophet (peace and blessings be upon him) on very cold days, then when it ceased, sweat would be dripping from his forehead.
