أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، - وَاللَّفْظُ لَهُ - عَنِ ابْنِ الْقَاسِمِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا قُلْتَ لِصَاحِبِكَ أَنْصِتْ وَالإِمَامُ يَخْطُبُ فَقَدْ لَغَوْتَ ‏"‏ ‏.‏
Translation
It was narrated from Abu Hurairah that

The Messenger of Allah (ﷺ) said: "If you say to your companion: 'Be quiet and listen' when the imam is delivering the Khutbah, you have engaged in idle speech."

Comment

The Book of the Prayer for the Two 'Eids - Sunan an-Nasa'i

Hadith Reference: Sunan an-Nasa'i 1577

Textual Analysis

The Prophet (ﷺ) explicitly prohibited any form of speech during the Friday khutbah, even commands for silence. This demonstrates the absolute sanctity of the imam's sermon time.

Legal Ruling

Scholars unanimously agree that speaking during the khutbah is forbidden. The prohibition extends even to enjoining good or forbidding evil, as such speech distracts from the primary obligation of listening attentively.

Spiritual Wisdom

This teaching cultivates proper adab (etiquette) in the mosque. Silence during khutbah allows full concentration on divine guidance and prevents disturbance to other worshippers seeking spiritual benefit.

Practical Application

If one needs to quiet another, a gentle gesture suffices. The hadith emphasizes that the ends don't justify forbidden means - maintaining khutbah's sanctity takes precedence over correcting others verbally.
