حَدَّثَنَا عَمْرُو بْنُ عَبَّاسٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ جَابِرٍ ـ رضى الله عنه ـ جَاءَ أَعْرَابِيٌّ النَّبِيَّ صلى الله عليه وسلم فَبَايَعَهُ عَلَى الإِسْلاَمِ، فَجَاءَ مِنَ الْغَدِ مَحْمُومًا، فَقَالَ أَقِلْنِي، فَأَبَى ثَلاَثَ مِرَارٍ، فَقَالَ ‏"‏ الْمَدِينَةُ كَالْكِيرِ، تَنْفِي خَبَثَهَا، وَيَنْصَعُ طَيِّبُهَا ‏"‏‏.‏
Translation
Narrated Jabir

A bedouin came to the Prophet (ﷺ) and gave a pledge of allegiance for embracing Islam. The next day he came with fever and said (to the Prophet (ﷺ) ), "Please cancel my pledge (of embracing Islam and of emigrating to Medina)." The Prophet (ﷺ) refused (that request) three times and said, "Medina is like a furnace, it expels out the impurities (bad persons) and selects the good ones and makes them perfect."

Virtues of Madinah - Sahih al-Bukhari 1883

A bedouin came to the Prophet (ﷺ) and gave a pledge of allegiance for embracing Islam. The next day he came with fever and said (to the Prophet (ﷺ) ), "Please cancel my pledge (of embracing Islam and of emigrating to Medina)." The Prophet (ﷺ) refused (that request) three times and said, "Medina is like a furnace, it expels out the impurities (bad persons) and selects the good ones and makes them perfect."

Commentary on the Hadith

This noble hadith establishes the sanctity of Madinah and its unique spiritual quality. The Prophet's comparison of Madinah to a furnace (kīr) indicates its power to purify souls, just as fire separates pure metal from dross.

The bedouin's request to rescind his pledge demonstrates the weakness of iman when faced with worldly hardship. The Prophet's refusal teaches us that religious commitments cannot be abandoned due to temporary difficulties.

Madinah's fever served as a test - exposing the bedouin's lack of sincerity while strengthening true believers. This illustrates how trials purify the Muslim community, separating those with firm faith from those with weak conviction.

The hadith also establishes that emigration to Madinah was an essential component of early Islam, and abandoning it was not permitted once the pledge was given, except for valid shar'i excuses.

Scholarly Insights

Imam al-Qurtubi notes: "The furnace metaphor indicates Madinah's role in testing people's faith. Just as fire reveals true gold, Madinah reveals true believers."

Ibn Hajar al-Asqalani explains: "The Prophet's refusal despite the bedouin's illness shows that worldly hardships don't nullify religious obligations. True faith persists through difficulty."

Al-Nawawi comments: "This hadith contains multiple wisdoms - the virtue of Madinah, the obligation of fulfilling pledges, and that trials purify the community of believers."
