It is narrated from Hazrat Saeed bin Al-Musayyib (may Allah have mercy on him) that the Holy Prophet Muhammad (peace and blessings be upon him) began to receive the revelation of the Qur'an at the age of forty-three. He stayed in Makkah Mukarramah for ten years and in Madinah Munawwarah for ten years. When the Prophet (peace and blessings be upon him) passed away, his blessed age was sixty-three years.
