Sayyiduna Awf bin Malik Ashja'i (may Allah be pleased with him) says: One day the Messenger of Allah (peace and blessings be upon him) came to us, while he had a staff in his hand. There were clusters of dates hanging in the mosque, and in one of the clusters there were dry and inferior dates. The Prophet (peace and blessings be upon him) struck that cluster with his staff and said: If the one giving this cluster in charity had wished, he could have given better charity from it. This person will eat only worthless dates on the Day of Resurrection. Then the Prophet (peace and blessings be upon him) turned towards us and said: O people of Madinah! A time will come when you will leave this city for forty years for the birds and wild beasts. The narrator says: I said that Allah knows best, but he said that by“(awaafi)”the Prophet (peace and blessings be upon him) meant birds and wild beasts. We used to say: Surely this is the same thing which the non-Arabs call“karaaki.”
