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."  

أَنَّ الْحَارِثَ بْنَ هِشَامٍ سَأَلَ رَسُولَ اللَّهِ ﷺ كَيْفَ يَأْتِيكَ الْوَحْىُ فَقَالَ رَسُولُ اللَّهِ ﷺ أَحْيَانًا يَأْتِينِي فِي مِثْلِ صَلْصَلَةِ الْجَرَسِ وَهُوَ أَشَدُّ عَلَىَّ وَأَحْيَانًا يَتَمَثَّلُ لِي الْمَلَكُ رَجُلاً فَيُكَلِّمُنِي فَأَعِي مَا يَقُولُ قَالَتْ عَائِشَةُ فَلَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَنْزِلُ عَلَيْهِ الْوَحْىُ فِي الْيَوْمِ الشَّدِيدِ الْبَرْدِ فَيَفْصِمُ عَنْهُ وَإِنَّ جَبِينَهُ لَيَتَفَصَّدُ عَرَقًا
