7211. Narrated Jabīr bin 'Abdullāh رَضِيَ اللَّهُ عَنْهُمَا: A bedouin gave the Bai'a (pledge) to Allāh's Messenger ﷺ for Islam. Then the bedouin got fever at Al-Madīna, he came to Allāh's Messenger ﷺ and said: "O Allāh's Messenger! Cancel my pledge." But Allāh's Messenger ﷺ refused. Then he came to him (again) and said, "O Allāh's Messenger! Cancel my pledge." But the Prophet ﷺ refused. The bedouin finally went out (of Al-Madīna) whereupon Allāh's Messenger ﷺ said, "Al-Madīna is like a pair of bellows (furnace), it cleanses its impurities and brightens and clears its good."
