Adi b. Hatim reported that the Messenger of Allah ﷺ made a mention of the Fire and sought refuge (with Allah against it). He turned aside his face three times and then said: Protect yourselves against Fire even if with half a date. But if you fail to find it (then protect yourselves against Fire) with the help of a pleasant word).

وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرِو بْنِ مُرَّةَ، عَنْ خَيْثَمَةَ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ ذَكَرَ النَّارَ فَتَعَوَّذَ مِنْهَا وَأَشَاحَ بِوَجْهِهِ ثَلاَثَ مِرَارٍ ثُمَّ قَالَ " اتَّقُوا النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ فَإِنْ لَمْ تَجِدُوا فَبِكَلِمَةٍ طَيِّبَةٍ " .
