باب إِلْزَاقِ الْمَنْكِبِ بِالْمَنْكِبِ وَالْقَدَمِ بِالْقَدَمِ فِي الصَّفِّ

And An-Nu'man bin Bashir said, "I saw that every one of us used to put his heel with the heel of his companion." ​​
وَقَالَ النُّعْمَانُ بْنُ بَشِيرٍ رَأَيْتُ الرَّجُلَ مِنَّا يُلْزِقُ كَعْبَهُ بِكَعْبِ صَاحِبِهِ.

حَدَّثَنَا عَمْرُو بْنُ خَالِدٍ، قَالَ حَدَّثَنَا زُهَيْرٌ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ ‏‏.‏ وَكَانَ أَحَدُنَا يُلْزِقُ مَنْكِبَهُ بِمَنْكِبِ صَاحِبِهِ وَقَدَمَهُ بِقَدَمِهِ‏.‏
"‏ أَقِيمُوا صُفُوفَكُمْ فَإِنِّي أَرَاكُمْ مِنْ وَرَاءِ ظَهْرِي ‏"
Anas bin Malik:

The Prophet (ﷺ) said, "Straighten your rows for I see you from behind my back." Anas added, "Everyone of us used to put his shoulder with the shoulder of his companion and his foot with the foot of his companion."
