I heard the Prophet (ﷺ) saying, "Protect yourself from (Hell) Fire, by giving of half of a date (in charity)".

[Al-Bukhari and Muslim].

In another narration 'Adi bin Hatim (May Allah be pleased with him) reported Messenger of Allah (ﷺ) as saying: "Allah will surely speak with everyone of you without an interpreter. He (the man) will look at his right side and will see nothing but (the deeds) which he had done before, and he will look to his left side and will see nothing but (the deeds) which he had done before. Then he will look in front of him and will find nothing but Hell-fire facing him. So protect (yourselves) from (Hell) Fire, by giving in charity even half a date; and if he does not finds it, then with a kind word".
