The period of Nabi’s ﷺ (peace and blessings be upon him) nubuwat

In the knowledge of Allah ﷻ (exalted is His majesty), Nabi ﷺ (peace and blessings be upon him) received nubuwat before all the other Ambiyaa. However, in this world, Nabi ﷺ (peace and blessings be upon him) received nubuwat at the age of forty years and one day according to the lunar calendar.

Nabi ﷺ (peace and blessings be upon him) mentions: “I was in the cave of Hira when Jibraeel عليه السلام (peace be upon him) came to me and said, ’اقْرَأْ (read)’. I told him that I do not know how to read. Jibraeel عليه السلام (peace be upon him) then squeezed me very tightly and told me: ‘Read.’ Again I told him that I could not read. He then squeezed me for the second time and told me to read. Again I told him that I could not read. Jibraeel عليه السلام (peace be upon him) then squeezed me for the third time and again asked me to read. I then asked him what should I read. At that time Jibraeel عليه السلام (peace be upon him) recited the aayaat (verses) of Surah Iqra: ٱقْرَأْ بِٱسْمِ رَبِّكَ ٱلَّذِى خَلَقَ up to مَا لَمْ يَعْلَمْ.” This was the first revelation received by Rasulullah ﷺ (peace and blessings be upon him).
