The Holy Prophet (S.A.W.) and the Sour Grapes

One day a poor man brought a bunch of grapes to the Holy Prophet Muhammad (S.A.W.) as a gift.
The Holy Prophet (S.A.W.) ate one, two, three and then the whole bunch of grapes by himself. He did not offer grapes to anyone present.
The poor man who brought those grapes was very pleased and left.
One of the companions asked, “O prophet of Allah! How come you ate all the grapes by yourself and did not offer to any one of us present?
The Holy Prophet (S.A.W.) smiled and said, “I ate all the grapes by myself because the grapes were sour. If I would have offered you, you might have made funny faces and that would have hurt the feelings of that poor man. I thought to myself that it is better that I eat all of them cheerfully and please the poor man. I did not want to hurt the feelings of that poor man.”
