Muslim reported from Anas ibn Malik that the Messenger of Allaah (sallallaahu `alayhi wasallam) said:
“In Paradise there is a market to which the people will come every Friday, then a wind will come from the north and blow on their faces and clothes, and they will increase in beauty. Then they will return to their wives, who will also have increased in beauty. Their wives will say to them: “By Allaah, you increased in beauty after you left us,” and they will say, “And you too, by Allaah you have increased in beauty since you left us.”
An-Nawawi commented on this hadeeth: “What is meant by a market is a gathering place where the people will come together, just as they gather in marketplaces in this world. Gathering together every Friday means that they will meet once a week, or what approximates to once a week; there will be no real weeks there, as there will be no sun or moon or days. The wind of Paradise was described specifically as being the north winds, because for the Arabs [of the Arabian peninsula] this is the wind that brings rain, coming from the direction of Syria, so they always hoped from a wind coming from north. In the hadeeth this wind is called al-Muthirah, i.e. something that carries things, because it will blow the sand or dust of Paradise into their faces, which is Musk.”
