Is it permissible to raise the price of goods purchased before the rise in the dollar exchange rate, based on the current rise in the dollar exchange rate which has affected the wholesale price?

There is no objection to raising the price of goods, whether the dollar's value increases or not. This is because there is no fixed limit for the amount of profit in Islam; rather, it is left to what the buyer and seller agree upon. However, it is commendable to be lenient in selling, as stated in the Hadith: "May Allah have mercy upon a man who is lenient when he sells, when he buys, and when he demands."
