Allah’s Messenger (ﷺ) started receiving Divine Inspiration at the age of forty. The Archangel Jibril peace be upon him went to him when he was in the cave Hira on a Monday on the seventeenth day of Ramadan. “The angel said: Recite, to which he replied: I am not lettered. He took hold of him and pressed him, till he was in pain. Thereafter he let him go and said: Recite. He said: I am not lettered”, three times. He then said: (Read, ˹O Prophet, ˺ in the Name of your Lord Who created— created humans from a clinging clot. Read! And your Lord is the Most Generous, Who taught by the pen— taught humanity what they knew not.)
بعث صلى الله عليه وسلم لأربعين سنة، فنزل عليه الملك جبريل عليه السلام، بحراء يوم الاثنين لسبع عشرة ليلة خلت من رمضان، فلما نزل عليه الملك قال له : اقرأ .. قال: لست بقارئ، فغطاه الملك حتى بلغ منه الجهد ، ثم قال له اقرأ..فقال: لست بقارئ ثلاثا. ثم قال:( اقرأ باسم ربك الذي خلق * خلق الإنسان من علق * اقرأ وربك الأكرم* الذي علم بالقلم * علم الانسان مالم يعلم ) العلق:1_5.
