Al-Madeenah is a blessed land, purified by Allah from impurities and evils, and chosen to be the land to which the Prophet ﷺ migrated, the cradle of His call, and a refuge for His righteous servants. In this hadeeth, Jaabir ibn ‘Abdullah(may Allah be pleased with him) told us that a Bedouin man (desert dweller) migrated to Al-Madeenah and went to the Prophet ﷺ to give him the Bay‘ah (pledge of allegiance) to adhere to Islam. The Arabic word Bay‘ah means a contract or covenant, and it is given that name because it is similar to a financial trade-off in the sense that each of the two parties offers the other something in exchange. The Prophet ﷺ offered them the promise of reward and they offered in return their commitment to his obedience. This Bedouin man had a fever on the following day, and went back to the Prophet ﷺ to cancel his Bay‘ah! Apparently, he did not want to give up Islam, otherwise he would not have bothered to go back to theProphet ﷺ and seek his permission. Rather, he wanted to back out of his commitment to the migration, but the Prophet ﷺ refused, because backing out of the migration is a major sin. This is why the Prophet ﷺ said in another hadeeth, “O Allah, complete for my Companions their migration, and do not cause them to turn back upon their heels.” [Al-Bukhaaree and Muslim]. Moreover, his act implies having ill thoughts about Allah, Exalted is He, because he assumed that he had a fever because he had given the pledge of alligance to the Prophet ﷺ (to migrate to Al-Madeenah), and thought that if he ﷺ released him from his commitment, he would be cured from the fever! Therefore, he went to the Prophet ﷺ with such a request, and this indicated his keenness, but he ﷺ refused. Despite the Prophet’s ﷺrefusal, the man left Al-Madeenah, and thereupon he ﷺ remarked that Al-Madeenah is like a furnace, in that it expels out the impurities (bad people), chooses only the good ones and refines them. In this hadeeth, he ﷺ likened Al-Madeenah to a pair of bellows made from (wood and) leather used by blacksmiths to push air into the fire to allow the furnace to reach a high temperature,so as to make the iron melt and remove its impurities. Similarly, Al-Madeenah expels the wicked people and purifies itself from their evil to manifest its perfect purity. This is a metaphor of the faith of the true and sincere believers among its inhabitants. This is a good metaphor, because thebellows is used to blow on the fire to supply air to remove the black smoke and ashes from the fire, leaving only the burning embers. This is the meaning if the hadeeth referred to the actual bellows used by the blacksmith to produce a strong blast of air to heat up the fire. However, if the intended meaning is the furnace itself, the hadeeth would mean that this place, given its high temperature, removes all impurities from iron, silver and gold to produce pure iron, silver and gold. Likewise, Al-Madeenah turns out the wicked people by means of fever, illness, poor livelihoods, and poverty to purify the ‘human self’ from the traces of indulgence in sinful desires, and thus refines the good people. It is noteworthy that this description does not apply to Al-Madeenah at all times, but is rather specific to the lifetime of the Prophet ﷺ, because none would leave Al-Madeenah to reside elsewhere except that he was a wicked person. After the Prophet’s death, some of the best people among his Companions (may Allah be pleased with them) moved out of Al-Madeenah and died in their new places of residence. This cannot be refuted by the fact that the hypocrites lived and died in Al-Madeenah and it did not expel them, because it was originally their homeland, and they did not inhabit it after embracing Islam or for religious reasons, but rather resided therein for the good livelihood opportunities there. The Prophet ﷺused this metaphor in reference to those who willingly committed themselves to Islam and then their hearts were corrupted. It is deduced from the hadeeth that whenever someone makes a covenant with Allah, committing himself or someone else to doing something, it is impermissible for him to release himself from such a commitment, because such an act involves disobedience to Allah, Exalted is He, who Says (that which means): {O you who have believed, fulfill [all] contracts.} [Quran 5:1]. .
