Narrated [Ibn 'Umar (RA)] : I said, "O Allah's Messenger, I sell camels at al-Baqi'. I sell for Dinars and take Dirhams (for them), and sell for Dirhams, and take Dinars (for them), I take this for that and give that for this (i.e. Dinars and Dirhams)." Allah's Messenger ( صلی اللہ علیہ وسلم ) replied, "There is no harm in taking them at the current rate so long as you do not separate leaving something still to be settled (from the exchange)." [Reported by al-Khamsah and al-Hakim graded it Sahih (authentic)] .
