عَنْ أَبِي صَالِحٍ ذَكْوَانَ عَنْ أَبِي هُرَيْرَةَ وَأَبِي سَعِيدٍ وَجَابِرٍ رَضِيَ اللَّهُ عَنْهُمْ أَوْ اثْنَيْنِ مِنْ هَؤُلَاءِ الثَّلَاثَةِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَهَى عَنِ الصَّرْفِ
It is narrated from Sayyiduna Abu Hurairah, Sayyiduna Abu Sa‘id, and Sayyiduna Jabir (may Allah be pleased with them), either from all three or from two of them, that the Noble Prophet (peace and blessings be upon him and his family) forbade the transaction of sarf (exchange of gold and silver).
