Sahih al-Bukhari 6416

Ali ibn Abdullah narrated to us: Muhammad ibn Abd al-Rahman Abu al-Mundhir al-Tufawi narrated to us, from Sulayman al-Amash, who said: Mujahid told me, from Abdullah ibn Umar, may Allah be pleased with them both, who said: The Messenger of Allah, peace and blessings be upon him, took me by the shoulder and said, ‘Be in this world as though you were a stranger or a traveler passing through.’ Ibn Umar used to say: When evening comes, do not expect to reach the morning; and when morning comes, do not expect to reach the evening. Take from your health for your illness, and from your life for your death.
