The Prophet's Madīnah is a blessed spot on earth. Allah rid it of impurities and chose it to be the place of Hijrah for the Prophet (may Allah's peace and blessings be upon him), the incubator of his mission and the foundation of his state. In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) informs that a time will come for the people when a man will call his cousin and relative, saying: "Come to prosperity", i.e., leave Madīnah and hasten to prosperity. By this, he meant that countries would be conquered by the Muslims, and thus, there would be abundant fortunes. Consequently, many of those who left the Hejaz and the Arab land would be inclined to the fortunes they found in these conquered countries and would take them as a homeland and invite their relatives in Madīnah to come to them, given the difficult living there. But in reality, staying in Madīnah is better for them as it is the sanctuary of the Messenger of Allah (may Allah's peace and blessings be upon him) and his refuge and the place where divine revelation and blessings descended if they only knew the religious benefits and results of staying in it, compared to which the worldly transient and fleeting fortunes they find in living elsewhere would seem trivial. Or the meaning: If they only had any knowledge, i.e., Would that they were among the people of knowledge - by way of emphasis and rebuke. Then the Prophet (may Allah's peace and blessings be upon him) took an oath, saying: "By the One in Whose Hand my soul is", and this is swearing by Allah, Who possesses the life and soul, "none amongst them will go out" i.e., none of those who live in it will abandon and leave it, disliking and being disinterested in it, or disinterested the reward for dwelling in it, except that Allah, the Glorified and Exalted, will make a better person than him will succeed him - who will be born in Madīnah or move to it from another place. Then the Prophet (may Allah's peace and blessings be upon him) mentioned that it banishes evil people from it, and they do not bear to live therein. Only the righteous believers bear to stay in it. Indeed, it does not leave in it anyone in whose heart there is wickedness and corruption. Rather, it distinguishes him from people with sincere hearts and drives him out, as fire separates bad iron from good one. A bellows is the leather by which the blacksmith blows into the fire. The Hour will not occur until Madīnah banishes its evils just as a bellows eliminates the impurities of iron. The impurities of iron are the dirt and filth extricated therefrom by fire. It is said: It is meant to refer here to some of the hypocrites who lived during the lifetime of the Prophet (may Allah's peace and blessings be upon him). Otherwise, many righteous and virtuous people left Madīnah after the Prophet's lifetime, and some wicked and evil people remained therein. It is also said That Madīnah banishes its evils, which probably applies to the time of the Dajjāl and may also apply to different eras. The Hadīth demonstrates some merits of Madīnah. It includes one of the signs proving the Prophet's prophethood..
