أَخْبَرَنَا نَصْرُ بْنُ عَلِيٍّ، عَنْ خَالِدٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْمُحِلِّ، عَنْ عَدِيِّ بْنِ حَاتِمٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " اتَّقُوا النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ " .
It was narrated from 'Adiyy bin Hatim that the Prophet said: "Protect yourselves from the Fire, even with half a date."
