Adi bin Hatim reported,

The Prophet ﷺ mentioned the Fire and turned his face away, seeking refuge from it. Then he mentioned the Fire again and turned his face away, seeking refuge from it. Then he said, "Guard yourselves from the Fire, even with half a date, and whoever cannot find that, then with a kind word."
