[Machine] I used to embroider for the wives of the Prophet ﷺ and they told me that they heard the Messenger of Allah ﷺ saying: "Gold is traded for gold, silver for silver, like for like. Whoever adds or seeks to add more has engaged in usury."  

أحمد:٢٢٣٣٠حَدَّثَنَا أَبُو النَّضْرِ حَدَّثَنَا أَبُو جَعْفَرٍ عَنْ يَحْيَى الْبَكَّاءِ عَنْ أَبِي رَافِعٍ قَالَ

كُنْتُ أَصُوغُ لِأَزْوَاجِ النَّبِيِّ ﷺ فَحَدَّثْنَنِي أَنَّهُنَّ سَمِعْنَ رَسُولَ اللهِ ﷺ يَقُولُ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ فَمَنْ زَادَ أَوْ اسْتَزَادَ فَقَدْ أَرْبَى
