The Call: 610 A.D.
By the time the Holy Prophet (P.B.U.H) was 40 years old, he was spending more and more time in Mount Hira where meditated for days and nights.
One-night Angel Gabriel came and said “Read.”
These were the first words the Allah revealed to His Messenger. the Holy Prophet (P.B.U.H) replied “I cannot read.” To which Angel Gabriel repeated the word ‘read.’
After the episode, the Holy Prophet (P.B.U.H) came home trembling and pale. He told Hazrat Khadija about the incident over which she reacted calmly. This shows how sincere she was to him.
After that she went to her cousin named Waraqa and narrated the whole story. Her cousin was now convinced that indeed he was the Last Prophet that was promised.
Afterwards started the series of revelations that we have today in the shape of Quran.
