How do the people of Paradise increase in beauty and handsomeness in the market of Paradise on Friday: Does that include clothing and appearance, or do their forms change for the better? And what is meant by "forms" in this context?

They will come to a market in Paradise every Friday. A northern wind will blow, increasing their beauty and handsomeness in their appearance. They will return to their families, finding them also increased in beauty and handsomeness. Other hadiths state that the market will take place after seeing Allah Almighty, and that the increase in beauty and handsomeness is not limited to the wind, but rather it is something that may be caused by seeing Allah Almighty.
