In the hadith narrated of the authority of Abu Hurairah (RA) the Messenger of Allah (ﷺ) is reported to have said. while in the hadith narrated by Bakr (the words are like this): He heard the Messenger of Allah (ﷺ) as saying: Just see, can anything of his filthiness remain (on the body of) any one of you if there were a river at his door in which he washed himself five times daily? They, said: Nothing of his filthiness will remain (on his body). He said: That is like the five prayers by which Allah obliterates sins.

Hadith Commentary: Benefits and Issues: By performing prayer (salah), a person's minor sins (saghirah) are forgiven, because the effects of minor sins manifest on the outward body, and thus their removal is easy. Just as if dirt on the body does not penetrate the pores or if filth is not absorbed into the clothing, then washing it is easy. However, if the dirt that attaches to the body seeps inside, then even cleaning it with soap is not easy. The effects of major sins (kabirah) impact a person's heart, and therefore, they are not forgiven except through repentance (tawbah) or the special mercy of Allah Ta'ala.

´Jabir said:` "The Messenger of Allah said: 'A town-dweller should not sell for a direst-dweller. Leave the people alone and let Allah provide for them from one another."" (Sahih )
Hafiz Muhammad Ameen
The purpose is that transactions should proceed in a natural manner. Artificial scarcity should not be created, nor should inflation be caused through hoarding; rather, as production comes in, it should be sold in the market and continue to reach those in need. It is evident that if a city dweller sells the goods of a villager, he will engage in hoarding and create artificial scarcity so that the produce can be sold at a higher price for his own benefit.
