It was narrated that Ibn Umar said: “I came to the Prophet صلی اللہ علیہ وآلہ وسلم and said: ‘Wait, I want to ask you something. I sell camels in Al Baqi’ with a price set in Dinars but I accept Dirhams instead.’ He said: ‘There is nothing wrong with it if you take the price on that day, unless you depart when there is still unfinished business between you both (buyer and seller).” (Hasan)
