Sunan Ibn Majah 172
It was narrated from Abu Zubair that Jabir bin 'Abdullah said:
"The Messenger of Allah was in Ji'ranah and he was distributing gold nuggets and spoils of war which were in Bilal's lap. A man said: 'Do justice, O Muhammed!' He said: 'Woe to you! Who will do justice after me if I do not do justice?' 'Umar said: 'O Messenger of Allah! Let me strike the neck of this hypocrite!' The Messenger of Allah said: 'This man has some companions who recite the Qur'an but it does not go any deeper than their collarbones. They will pass through Islam like an arrow passing through its target.'"
حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، أَنْبَأَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بِالْجِعِرَّانَةِ وَهُوَ يَقْسِمُ التِّبْرَ وَالْغَنَائِمَ وَهُوَ فِي حِجْرِ بِلاَلٍ فَقَالَ رَجُلٌ اعْدِلْ يَا مُحَمَّدُ فَإِنَّكَ لَمْ تَعْدِلْ ‏.‏ فَقَالَ ‏"‏ وَيْلَكَ وَمَنْ يَعْدِلُ بَعْدِي إِذَا لَمْ أَعْدِلْ ‏"‏ ‏.‏ فَقَالَ عُمَرُ دَعْنِي يَا رَسُولَ اللَّهِ حَتَّى أَضْرِبَ عُنُقَ هَذَا الْمُنَافِقِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ إِنَّ هَذَا فِي أَصْحَابٍ - أَوْ أُصَيْحَابٍ - لَهُ يَقْرَءُونَ الْقُرْآنَ لاَ يُجَاوِزُ تَرَاقِيَهُمْ يَمْرُقُونَ مِنَ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ ‏"‏ ‏.‏
