حَدَّثَنَا حَجَّاجٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي عَلِيُّ بْنُ مُدْرِكٍ، عَنْ أَبِي زُرْعَةَ، عَنْ جَرِيرٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ لَهُ فِي حَجَّةِ الْوَدَاعِ ‏"‏ اسْتَنْصِتِ النَّاسَ ‏"‏ فَقَالَ ‏"‏ لاَ تَرْجِعُوا بَعْدِي كُفَّارًا يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ ‏"‏‏.‏
Translation
Narrated Jarir

The Prophet (ﷺ) said to me during Hajjat-al-Wida`: Let the people keep quiet and listen. Then he said (addressing the people), "Do not (become infidels) revert to disbelief after me by striking the necks (cutting the throats) of one another (killing each other).

Comment

Hadith Commentary: The Prohibition of Mutual Killing

This profound narration from Sahih al-Bukhari (Book: Knowledge, Hadith: 121) was delivered during the Farewell Pilgrimage, a moment of immense significance in Islamic history. The Prophet Muhammad (ﷺ) commanded silence to ensure his final counsel reached all present with absolute clarity and authority.

Contextual Significance

The Farewell Pilgrimage marked the completion of the Islamic message. The Prophet's instruction to "let the people keep quiet and listen" underscores the gravity of what followed. This was not ordinary advice but fundamental guidance for preserving the Muslim community's integrity after his passing.

The timing reveals divine wisdom - delivering this warning when the entire Muslim community was gathered during pilgrimage ensured maximum reach and impact, making it a collective covenant binding upon all believers.

Scholarly Interpretation

Classical scholars like Ibn Hajar al-Asqalani explain that "reverting to disbelief" through mutual killing refers to acts that lead to the spiritual state of disbelief, even if the perpetrator remains within the fold of Islam nominally. The imagery of "striking the necks" powerfully conveys the severity of Muslims killing one another.

Imam al-Nawawi emphasizes that this hadith establishes the sanctity of Muslim life and the grave sin of taking it unlawfully. The prohibition extends beyond physical killing to include character assassination, spreading fitnah (discord), and any action that destroys communal harmony.

Legal and Spiritual Implications

This narration forms the foundation for Islamic rulings prohibiting civil war, rebellion against legitimate authority without just cause, and any form of violence that disrupts social order. Scholars derive from this that preserving Muslim unity and life takes precedence over many other religious considerations.

The warning connects mutual killing to disbelief because such actions negate the brotherhood that Islam establishes among believers. When Muslims kill each other, they effectively reject the fundamental principle of Islamic fraternity that the Prophet (ﷺ) tirelessly worked to establish.

Contemporary Relevance

This hadith serves as an eternal reminder for Muslims to resolve differences through dialogue and legal means rather than violence. It condemns sectarian strife, tribal warfare, and political conflicts that lead to bloodshed within the Muslim community.

The Prophetic warning remains critically relevant today, calling Muslims to prioritize unity, practice tolerance, and remember that internal conflict constitutes a betrayal of the Prophet's final testament to his nation.
