Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ وَحَجَّاجٌ قَالَا حَدَّثَنَا شُعْبَةُ عَنْ سِمَاكِ بْنِ حَرْبٍ قَالَ سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ يَقُولُ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُسَوِّي الصَّفَّ حَتَّى يَجْعَلَهُ مِثْلَ الرُّمْحِ أَوْ الْقَدَحِ قَالَ فَرَأَى صَدْرَ رَجُلٍ نَاتِئًا فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا عِبَادَ اللَّهِ لَتُسَوُّنَّ صُفُوفَكُمْ أَوْ لَيُخَالِفَنَّ اللَّهُ بَيْنَ وُجُوهِكُمْ.
English Translation
Muhammad b. Ja'far and Hajjaj told us, they said: Shu'ba told us, from Simak b. Harb, who said: I heard al-Nu'man b. Bashir say: The Messenger of Allah, peace and blessings be upon him, used to straighten the row until he made it like a spear or an arrow. He said: Then he saw a man's chest protruding, so the Messenger of Allah, peace and blessings be upon him, said: "O servants of Allah, you shall straighten your rows, or Allah will surely turn your faces against one another."
