It is narrated from Hazrat Aisha (may Allah be pleased with her) that once Hazrat 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 revelation comes to me with a sound like the ringing of a bell; this form is the hardest upon me, but when this state departs from me, I have understood the divine message. And sometimes the angel comes to me in the form of a man and speaks to me, and I remember what he says."
