حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ عَنْ مَالِکٍ عَنْ مُحَمَّدِ بْنِ الْمُنْکَدِرِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ أَعْرَابِيًّا بَايَعَ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَی الْإِسْلَامِ فَأَصَابَهُ وَعْکٌ فَقَالَ أَقِلْنِي بَيْعَتِي فَأَبَی ثُمَّ جَائَهُ فَقَالَ أَقِلْنِي بَيْعَتِي فَأَبَی فَخَرَجَ فَقَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةُ کَالْکِيرِ تَنْفِي خَبَثَهَا وَيَنْصَعُ طِيبُهَا
صحیح بخاری · Hadith 7209
Narrated Jabir bin `Abdullah: A bedouin gave the Pledge of allegiance to Allah's Apostle for Islam and the bedouin got a fever where upon he said to the Prophet "Cancel my Pledge." But the Prophet refused. He came to him (again) saying, "Cancel my Pledge.' But the Prophet refused. Then (the bedouin) left (Medina). Allah's Apostle said: "Medina is like a pair of bellows (furnace): It expels its impurities and brightens and clears its good."
