Narrated Awf ibn Malik: The Messenger of Allah ﷺ entered upon us in the mosque, and he had a stick in his hand. A man hung there a bunch of hashaf. He struck the bunch with the stick, and said: If the owner of this sadaqah (alms) wishes to give a better one than it, he would give. The owner of this sadaqah will eat hashaf on the Day of Judgment.
This hadith also teaches us about gratitude; even though it was not much, the owner still gave what he could as sadaqah or charity out of his own free will and this act was appreciated by Allah SWT. We can learn from this to always show gratitude for whatever we have been blessed with no matter how small it may seem.
