كتاب بدء الوحى
Read the English translation first, with the original Arabic directly underneath.
Narrated 'Aisha:
(the mother of the faithful believers) Al-Harith bin Hisham asked Allah's Messenger (ﷺ) "O Allah's Messenger (ﷺ) ! How is the Divine Inspiration revealed to you?" Allah's Messenger (ﷺ) 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 comes in the form of a man and talks to me and I grasp whatever he says." 'Aisha added: Verily I saw the Prophet (ﷺ) being inspired divinely on a very cold day and noticed the sweat dropping from his forehead (as the Inspiration was over).
أَحْيَانًا يَأْتِينِي مِثْلَ صَلْصَلَةِ الْجَرَسِ ـ وَهُوَ أَشَدُّهُ عَلَىَّ ـ فَيُفْصَمُ عَنِّي وَقَدْ وَعَيْتُ عَنْهُ مَا قَالَ، وَأَحْيَانًا يَتَمَثَّلُ لِيَ الْمَلَكُ رَجُلاً فَيُكَلِّمُنِي فَأَعِي مَا يَقُولُ
