At what age did the Holy Prophet Muhammad (SAW) receive the first revelation (Wahi)?

Prophet Muhammad (SAW) received the very first revelation from Allah at the age of 40, a moment that changed not only his life but the course of human history. Before this revelation, the Prophet (SAW) spent many years in deep reflection, contemplation, and spiritual searching. He would often retreat to the Cave of Hira, located on the mountain of Jabal al-Noor near Makkah. This peaceful and secluded place allowed him to reflect upon the moral decline and injustices spreading in society. His heart was already inclined toward truth, purity, and righteousness, and he was known among the people as Al-Ameen (the trustworthy) and As-Sadiq (the truthful).

At the age of 40, during one of his periods of retreat in Hira, the Angel Jibreel (AS) appeared with the first revelation. The words revealed were from Surah Al-Alaq: “Iqra bismi rabbika allathee khalaq”—Read in the name of your Lord who created. These were the opening verses of the Quran and marked the beginning of his prophethood. This moment was overwhelming for him, and he returned home to Hazrat Khadijah (RA), who comforted and reassured him, becoming the first believer in Islam.

The age of 40 carries special significance in many religious and spiritual traditions. It represents maturity, wisdom, and readiness for responsibility. By this age, Prophet Muhammad (SAW) had developed a strong moral character, deep compassion, and leadership qualities, making him fully prepared for the divine mission ahead. For Muslims, remembering that the first revelation came at age 40 is essential, as it highlights the beginning of Islamic teachings and the start of the Prophet’s (SAW) 23-year mission of spreading the message of Allah. This question appears frequently in Islamic Studies exams because it marks one of the most important turning points in Islamic history.
