حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرٍو، عَنْ مُصْعَبٍ، قَالَ سَأَلْتُ أَبِي ‏{‏قُلْ هَلْ نُنَبِّئُكُمْ بِالأَخْسَرِينَ أَعْمَالاً‏}‏ هُمُ الْحَرُورِيَّةُ قَالَ لاَ، هُمُ الْيَهُودُ وَالنَّصَارَى، أَمَّا الْيَهُودُ فَكَذَّبُوا مُحَمَّدًا صلى الله عليه وسلم وَأَمَّا النَّصَارَى كَفَرُوا بِالْجَنَّةِ وَقَالُوا لاَ طَعَامَ فِيهَا وَلاَ شَرَابَ، وَالْحَرُورِيَّةُ الَّذِينَ يَنْقُضُونَ عَهْدَ اللَّهِ مِنْ بَعْدِ مِيثَاقِهِ، وَكَانَ سَعْدٌ يُسَمِّيهِمُ الْفَاسِقِينَ‏.‏

Narrated Mus`ab:I asked my father, "Was the Verse:-- 'Say: (O Muhammad) Shall We tell you the greatest losers in respect of their deeds?'(18.103) revealed regarding Al-Haruriyya?" He said, "No, but regarding the Jews and the Christians, for the Jews disbelieved Muhammad and the Christians disbelieved in Paradise and say that there are neither meals nor drinks therein. Al- Hururiyya are those people who break their pledge to Allah after they have confirmed that they will fulfill it, and Sa`d used to call them 'Al-Fasiqin (evildoers who forsake Allah's obedience)
