question #1 Sahih Muslim 1077, Book 12, Hadith 228 : What is the significance of distinguishing between gifts and charity in Islamic teachings?

Whenever the Messenger of Allah (ﷺ) was presented with food, he asked about it, If he was told that it was a gift, he ate out of that, and if he was told that it was a sadaqa he did not eat out of that.
