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  

"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)   

عَنِ النَّبِيِّ ﷺ قَالَ الْفِضَّةُ بِالْفِضَّةِ مِثْلًا بِمِثْلٍ وَزْنًا بِوَزْنٍ وَالذَّهَبُ بِالذَّهَبِ وَزْنًا بِوَزْنٍ مِثْلًا بِمِثْلٍ فَمَنْ زَادَ فَهُوَ رِبًا  

[Machine] I heard the Messenger of Allah ﷺ, twice, on the pulpit saying, "Gold is to be exchanged for gold, silver for silver, in equal amounts"  

سَمِعْتُ رَسُولَ اللهِ ﷺ مَرَّتَيْنِ عَلَى الْمِنْبَرِ يَقُولُ الذَّهَبُ بِالذَّهَبِ وَالْفِضَّةُ بِالْفِضَّةِ وَزْنًا بِوَزْنٍ  

"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»  

"الذَّهَبُ بالذهبِ، والفِضَّةُ بالفضَّة، وَزنًا بوَزْنِ. فَمَنْ زَادَ أَو استَزَادَ فَقَدْ أَرْبَى".  

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