Sunan Ibn Majah Book 8, Hadith 1821

حَدَّثَنَا أَبُو بِشْرٍ، بَكْرُ بْنُ خَلَفٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ عَبْدِ الْحَمِيدِ بْنِ جَعْفَرٍ، حَدَّثَنِي صَالِحُ بْنُ أَبِي عَرِيبٍ، عَنْ كَثِيرِ بْنِ مُرَّةَ الْحَضْرَمِيِّ، عَنْ عَوْفِ بْنِ مَالِكٍ الأَشْجَعِيِّ، قَالَ خَرَجَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ وَقَدْ عَلَّقَ رَجُلٌ قِنَاءً أَوْ قِنْوًا وَبِيَدِهِ عَصًا فَجَعَلَ يَطْعَنُ بِذَلِكَ يُدَقْدِقُ فِي ذَلِكَ الْقِنْوِ وَيَقُولُ ‏ "‏ لَوْ شَاءَ رَبُّ هَذِهِ الصَّدَقَةِ تَصَدَّقَ بِأَطْيَبَ مِنْهَا إِنَّ رَبَّ هَذِهِ الصَّدَقَةِ يَأْكُلُ الْحَشَفَ يَوْمَ الْقِيَامَةِ ‏"‏ ‏.‏

It was narrated that:Awf bin Malik Al-Ashja'i said: “The Messenger of Allah went out, and a man had hung up one or more bunches of dates. He (the Prophet) had a stick in his hand and he started hitting that bunch of dates repeatedly, saying: 'If the owner of these dates wanted to give in charity, he should have given something better than these. The owner of this charity will eat rotten and shriveled dates on the Day of Resurrection.' ”
