I heard the the Messenger of Allah ﷺ saying: "Protect yourself from Hellfire even by giving half a date ˹in charity˺."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: «اتَّقُوا النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ۔»  

The Prophet ﷺ said, "There will be none among you but will be talked to by Allah on the Day of Resurrection, without there being an interpreter between him and Him (Allah) . He will look and see nothing ahead of him, and then he will look (again for the second time) in front of him, and the (Hell) Fire will confront him. So, whoever among you can save himself from the Fire, should do so even with one half of a date (to give in charity).  

قَالَ النَّبِيُّ ﷺ مَا مِنْكُمْ مِنْ أَحَدٍ إِلاَّ وَسَيُكَلِّمُهُ اللَّهُ يَوْمَ الْقِيَامَةِ لَيْسَ بَيْنَ اللَّهِ وَبَيْنَهُ تُرْجُمَانٌ ثُمَّ يَنْظُرُ فَلاَ يَرَى شَيْئًا قُدَّامَهُ ثُمَّ يَنْظُرُ بَيْنَ يَدَيْهِ فَتَسْتَقْبِلُهُ النَّارُ فَمَنِ اسْتَطَاعَ مِنْكُمْ أَنْ يَتَّقِيَ النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ
