Jami` at-Tirmidhi 1833
جامع الترمذي#1833SahihNarrated Abu Dharr: That the Messenger of Allah (ﷺ) said: "Let one of you not consider any good to be insignificant. If he has nothing, then let him meet his brother with a smiling face. If you buy some meat or cook something in a pot, then increase its broth, and serve some of it to your neighbor." [Abu 'Eisa said:] This Hadith is Hasan Sahih. Shu'bah reported it from Abu 'Imran Al-Jawni
