It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said: "Revelation was sent down upon the Prophet (peace and blessings be upon him) when he (peace and blessings be upon him) was forty years old. Then he (peace and blessings be upon him) stayed in Makkah for thirteen years and in Madinah for ten years, and he (peace and blessings be upon him) passed away at the age of sixty-three."
