Musnad Ahmad Hadith 390

`Umar (رضي الله عنه) heard that when Sa`d built the palace, he said. Now there will be no more noise. ‘Umar sent Muhammad bin Maslamah to him, and when he arrived he took out some kindling and lit a fire, and he bought some wood for a dirham. It was said to Sa`d: A man has done such and such. He said: That is Muhammad bin Maslamah. He went out to him and swore by Allah that he never said that. He said: We will convey from you what you have said and we will do as we were instructed. So he burned the door. Then he [Sa`d] offered some supplies (to the envoy) but he refused. He left at midday and went to ‘Umar(رضي الله عنه), and he went and came back within nineteen days. He said: Were it not that I think well of you, I would have thought that you did not convey my message. He said: Yes I did convey it, he conveys his salam and apologises, and he swore by Allah that he did not say that. He said: Did he give you any provisions? He said: No. He said: What prevented you from supplying (sufficient, provisions to me yourself? He said: I did not want to instruct that you be given the cold whilst I had the hot [i.e., I could not have given you what you wanted of food and enjoyed plentiful food myself, when around me are the people of Madinah who are starving, for I heard the Messenger of Allah (ﷺ) say: `No man should eat his fill when his neighbour is going without.”
