It is narrated from Hazrat Awf (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) came to us, and in his blessed hand was a staff. At that time, some bunches of dates were hanging in the mosque, among which there were also some unripe dates in one bunch. The Noble Prophet (peace and blessings be upon him) shook it with his staff and said, "If the one giving charity wished, he could have given more than this in charity. This person who gave charity will eat unripe dates on the Day of Resurrection." Then, turning towards us, he said, "By Allah, O people of Madinah! You will leave this city of Madinah for birds and beasts for forty years."
