22/15. Chapter:
Exchange and Selling Gold for Silver on the spot
Sahih Muslim
وَحَدَّثَنِيهِ أَبُو سَعِيدٍ الأَشَجُّ، حَدَّثَنَا الْمُحَارِبِيُّ، عَنْ فُضَيْلِ بْنِ غَزْوَانَ، بِهَذَا الإِسْنَادِ . وَلَمْ يَذْكُرْ " يَدًا بِيَدٍ " .
This hadith has been narrated on the authority of Fudail b. Ghazwan with the same chain of transmitters, but he made no mention of (payment being) made on the spot.
