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
English Translation
Ibn ‘Umar reported God’s Messenger as saying, ‘‘Set the rows in order, stand shoulder to shoulder, close the gaps, be pliant in the hands of your brethren, and do not leave openings for the devil. If anyone joins up a row God will join him up, but if anyone breaks a row God will cut him off.” Abu Dawud transmitted it and Nasa’i transmitted from “If anyone joins up ...” to the end.
