Amr bin Shu'ayb narrates from his father, and he from his grandfather (Sayyiduna Abdullah bin Amr (may Allah be pleased with them both)), that one night the Messenger of Allah (peace and blessings be upon him) was very restless. It was said to him (peace and blessings be upon him): What has kept you awake? He (peace and blessings be upon him) said: "I found a fallen date and ate it. Then I remembered that we also had some dates of charity, and now I do not know whether that date was from them or from the dates of my household. It is this that kept me awake." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.
