Al-Adab Al-Mufrad, 774
sahih· Al-Albani

Jabir said, "The Messenger of Allah, (ﷺ), was at al-Ji'rana on the Day of the Battle of Hunayn with the spoils in the custody of Bilal. The Prophet (ﷺ) was dividing them out. A man came up to him and said, 'Be just! You are not being just!' The Prophet (ﷺ) said, 'Bother you! Who will be just if I am not just?' 'Umar said, 'Messenger of Allah, let me strike off the head of the hypocrite!' The Prophet (ﷺ) said, 'This man is with his followers who recite the Qur'an and it does not go beyond their throats. They pass through the deen as an arrow passes through the target (i.e. nothing of it remains on the arrow).'"

حَدَّثَنَا عَلِيٌّ، قَالَ‏:‏ حَدَّثَنَا سُفْيَانُ قَالَ‏:‏ حَدَّثَنِي أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ قَالَ‏:‏ كَانَ رَسُولُ اللهِ صلى الله عليه وسلم يَوْمَ حُنَيْنٍ بِالْجِعْرَانَةِ، وَالتِّبْرُ فِي حِجْرِ بِلاَلٍ، وَهُوَ يَقْسِمُ، فَجَاءَهُ رَجُلٌ فَقَالَ‏:‏ اعْدِلْ، فَإِنَّكَ لاَ تَعْدِلُ، فَقَالَ‏:‏ وَيْلَكَ، فَمَنْ يَعْدِلُ إِذَا لَمْ أَعْدِلُ‏؟‏ قَالَ عُمَرُ‏:‏ دَعْنِي يَا رَسُولَ اللهِ، أَضْرِبُ عُنُقَ هَذَا الْمُنَافِقِ، فَقَالَ‏:‏ إِنَّ هَذَا مَعَ أَصْحَابٍ لَهُ، أَوْ‏:‏ فِي أَصْحَابٍ لَهُ، يَقْرَؤُونَ الْقُرْآنَ، لاَ يُجَاوِزُ تَرَاقِيَهُمْ، يَمْرُقُونَ مِنَ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ‏.‏
