Musannaf Ibn Abi Shaybah 37022 — Reports from our Prophet

Mujahid said: (After narrating this report) Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said to me: When morning comes, do not think about the coming evening, and when evening comes, do not think about the coming morning. Take benefit from your life before (the coming of) your death, and from your health before (the coming of) your sickness, for indeed you do not know what your name will be tomorrow (living or dead).
