It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that when the Prophet Muhammad (peace and blessings be upon him) was sent or when the revelation of the Qur'an began upon him, he was forty years old. After that, he spent thirteen years in Makkah Mukarramah and ten years in Madinah Munawwarah, and he passed away at the age of sixty-three.
