Gold is to be paid for by gold with equal weight, like for like, and silver is to be paid for by silver with equal weight, like for like. He who made an addition to it or demanded an addition dealt in usury.  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلاً بِمِثْلٍ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ مِثْلاً بِمِثْلٍ فَمَنْ زَادَ أَوِ اسْتَزَادَ فَهُوَ رِبًا  

"The Messenger of Allah said: 'Gold for gold, weight for weight, like for like; and silver for silver, weight for weight, like for like. Whoever gives more or takes more has engaged in Riba."'  

قَالَ رَسُولُ اللَّهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلاً بِمِثْلٍ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ مِثْلاً بِمِثْلٍ فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى  

[Machine] Narrated by the Prophet Muhammad ﷺ , he said, "Gold is bought with gold, silver is bought with silver, and paper money is bought with paper money, like for like, hand in hand. Whoever increases or is increased has indulged in riba (usury)."  

عَنِ النَّبِيِّ ﷺ قَالَ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَالْوَرِقُ بِالْوَرِقِ مِثْلًا بِمِثْلٍ يَدًا بِيَدٍ مَنْ زَادَ أَوْ ازْدَادَ فَقَدْ أَرْبَى  

[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."  

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

"The Messenger of Allah said: 'Gold for gold, weight for weight, like for like; and silver for silver, weight for weight, like for like. Whoever gives more or takes more has engaged in Riba."' (Using translation from Nasāʾī 4569)  

قَالَ رَسُولُ اللهِ ﷺ «الذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ فَمَنْ زَادَ أَوِ ازْدَادَ فَقَدْ أَرْبَى»  

Gold is to be paid for by gold with equal weight, like for like, and silver is to be paid for by silver with equal weight, like for like. He who made an addition to it or demanded an addition dealt in usury. (Using translation from Muslim 1588c)   

قَالَ رَسُولُ اللهِ ﷺ الذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ فَمَنْ زَادَ أَوِ اسْتَزَادَ فَقَدْ أَرْبَى  

"الذَّهَبُ بِالذَّهَبِ وَزْنًا بوَزْن، مِثْلًا بِمِثلٍ، والفِضةُ بالِفضةِ وَزْنًا بوزن مِثْلًا بِمِثلٍ، فمن زاد أَوْ استزاد فهو ربا".  

"الذَّهبُ بالذَّهَبِ وَزْنٌ بِوَزْنٍ، والفِضَّةُ بالفِضَّة وَزْنٌ بِوَزنٍ، الزَّايِدُ والمَزيدُ فِي النَّارِ".  

"الذَّهبُ بالذَّهَب، والوَرقُ بالورق، مِثْلًا بمِثْل، عَينًا بعَينٍ، وَزْنًا بوزْنٍ فَمنْ زَادَ أوْ ازْدَادَ فَقَدْ أَرْبَى".
