The reciter: The author (may Allah have mercy on him) transmitted, in the context of the hadiths in the chapter on the virtue of the first row and the command to complete the front rows, straighten them, and close the gaps in them:
" From Anas (may Allah be pleased with him), who said:

The iqama * had been uttered and God’s Messenger faced us and said, “Make your rows straight and stand close together, for l can see you behind my back.”

أُقيمت الصلاة، فأقبل علينا رسول الله صلى الله عليه وسلم بوجهه فقال : أقيموا صفوفكم وتراصوا، فإني أراكم من وراء ظهري

Mishkat al-Masabih 1086

Al-Bukhari narrated it with its wording, and Muslim with its meaning.
In a narration by al-Bukhari:

Everyone of us used to put his shoulder with the shoulder of his companion and his foot with the foot of his companion.

وكان أحدنا يُلزق منكبه بمنكب صاحبه وقدمه بقدمه

Sahih al-Bukhari 725

.
And from al-Nu'man ibn Bashir (may Allah be pleased with them both), who said: I heard the Messenger of Allah (peace and blessings be upon him) say:

Do not be irregular

لتسونَّ صفوفكم أو ليخالفن الله بين وجوهكم

Sunan Abi Dawud 663Sahih (Al-Albani)

Agreed upon by al-Bukhari and Muslim.
In a narration by Muslim:

The Messenger of Allah (ﷺ) directed us to keep our rows as straight as arrows. He continued stressing this until he realized that we had learnt it from him (recognized its significance). One day he came into the mosque and stood up. He was just about to say Takbir (Allah is Greater) when he noticed a man whose chest was projected from the row, so he said, "O slaves of Allah, you must straighten your rows or Allah will certainly put your faces in opposite directions."

أنَّ رسول الله صلى الله عليه وسلم كان يسوي صفوفنا حتى كأنما يسوي بها القِداح، حتى رأى أنا قد عقلنا عنه، ثم خرج يومًا فقام حتى كاد يكبر، فرأى رجلا باديا صدره من الصف، فقال : عباد الله لتسون صفوفكم أو ليخالفن الله بين وجوهكم

Riyad as-Salihin 1089

".

The Shaykh : In the name of Allah, the Most Gracious, the Most Merciful:
These hadiths are in the continuation of the chapter on establishing the rows, the exhortation to straighten them, and what is related to that:
From Abu Hurayrah (may Allah be pleased with him), that the Prophet (peace and blessings be upon him) used to straighten the rows, turning to the people and saying: : So he (peace and blessings be upon him and his family) commanded them to establish the rows, and informed them that he sees them from behind his back. This is among the special attributes of the Prophet (peace and blessings be upon him) that in this specific state, he sees the people from behind his back.
As for other than that, he is like others; he does not see anything from behind his back.
And he (peace and blessings be upon him) informed in the hadith of al-Nu'man ibn Bashir that either they would straighten the rows, or Allah would cause discord between their faces, so he said: .
The scholars differed regarding his saying: It was said: The meaning is that Allah will punish them by making their faces toward their backs, so their necks will twist. And it was said: The meaning is.
