Musannaf Ibn Abi Shaybah 37203 — The words of Umar bin al-Khattab

Zayd bin Aslam narrates from his father that he said: I was walking with Sayyiduna Umar bin al-Khattab (may Allah be pleased with him). He saw a fallen date and said: "Pick it up." I said: "What shall I do with this date?" Sayyiduna Umar (may Allah be pleased with him) said: "It is one date at a time that accumulates." So I picked it up. Then he passed by a heap of dates and said: "Throw this date in here."
