It is narrated from Sayyiduna Awf bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) came out holding a staff in his hand. There were bunches of dates (given in charity) hanging there, one of which was a bunch of poor, dried-up dates (hashaf). He (peace and blessings be upon him) struck that bunch with the staff and said: "What harm would it have done the giver of this charity if he had given something better than this? Indeed the owner of these dates will be given poor, dried-up dates to eat on the Day of Resurrection." Then he said: "By Allah, you will leave these orchards for forty years to the 'awafi.'" Then he said: "Do you know what the 'awafi' are?" They said: Allah and His Messenger know best. He (peace and blessings be upon him) said: "The birds and the beasts of prey." This hadith has a sahih (authentic) chain of narration, and the two Shaykhs (Bukhari and Muslim) did not record it.
