وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَقِيمُوا الصُّفُوفَ وَحَاذُوا بَين المنكاكب وَسُدُّوا الْخَلَلَ وَلِينُوا بِأَيْدِي إِخْوَانِكُمْ وَلَا تَذَرُوا فرجات للشَّيْطَان وَمَنْ وَصَلَ صَفًّا وَصَلَهُ اللَّهُ وَمَنْ قَطَعَهُ قطعه الله» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ مِنْهُ قَوْلَهُ: «وَمَنْ وَصَلَ صَفًّا» . إِلَى آخِرِهِ

Ibn ʿUmar reported that the Messenger of Allah (ﷺ) said: ‘Set the rows in order, align your shoulders, close the gaps, be gentle with your brothers, and leave no openings for Satan. Whoever joins a row, Allah joins him; whoever breaks a row, Allah cuts him off.’ Abu Dawud transmitted it; al-Nasaʾi transmitted from ‘Whoever joins a row’ to the end.
Notes and open questions — unreviewed
The Arabic specifies that al-Nasaʾi’s transmission begins with the clause about joining a row and continues to the end.
