أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ الْمُخَرِّمِيُّ، قَالَ حَدَّثَنَا أَبُو هِشَامٍ، قَالَ حَدَّثَنَا أَبَانُ، قَالَ حَدَّثَنَا قَتَادَةُ، قَالَ حَدَّثَنَا أَنَسٌ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم قَالَ " رَاصُّوا صُفُوفَكُمْ وَقَارِبُوا بَيْنَهَا وَحَاذُوا بِالأَعْنَاقِ فَوَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ إِنِّي لأَرَى الشَّيَاطِينَ تَدْخُلُ مِنْ خَلَلِ الصَّفِّ كَأَنَّهَا الْحَذَفُ " .
Muhammad ibn Abdullah ibn Al-Mubarak Al-Mukharrimi narrated to us: Abu Hisham narrated to us: Aban narrated to us: Qatadah narrated to us: Anas narrated to us, that the Prophet of Allah ﷺ said, 'Close your rows, bring them near one another, and align your necks. By the One in Whose hand is Muhammad's soul, I can see devils entering through the gaps in the row as if they were small sheep.'
Translation notes
The Arabic compares them to al-hadhaf, a small type of sheep.
