Al-Baqarah 2:275

ٱلَّذِينَ يَأۡكُلُونَ ٱلرِّبَوٰاْ لَا يَقُومُونَ إِلَّا كَمَا يَقُومُ ٱلَّذِي يَتَخَبَّطُهُ ٱلشَّيۡطَٰنُ مِنَ ٱلۡمَسِّۚ ذَٰلِكَ بِأَنَّهُمۡ قَالُوٓاْ إِنَّمَا ٱلۡبَيۡعُ مِثۡلُ ٱلرِّبَوٰاْۗ وَأَحَلَّ ٱللَّهُ ٱلۡبَيۡعَ وَحَرَّمَ ٱلرِّبَوٰاْۚ فَمَن جَآءَهُۥ مَوۡعِظَةٞ مِّن رَّبِّهِۦ فَٱنتَهَىٰ فَلَهُۥ مَا سَلَفَ وَأَمۡرُهُۥٓ إِلَى ٱللَّهِۖ وَمَنۡ عَادَ فَأُوْلَٰٓئِكَ أَصۡحَٰبُ ٱلنَّارِۖ هُمۡ فِيهَا خَٰلِدُونَ ٢٧٥

Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah. But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.

Al-Baqarah 2:278

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ ٱتَّقُواْ ٱللَّهَ وَذَرُواْ مَا بَقِيَ مِنَ ٱلرِّبَوٰٓاْ إِن كُنتُم مُّؤۡمِنِينَ ٢٧٨

O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers.

Āl-‘Imrān 3:130

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَأۡكُلُواْ ٱلرِّبَوٰٓاْ أَضۡعَٰفٗا مُّضَٰعَفَةٗۖ وَٱتَّقُواْ ٱللَّهَ لَعَلَّكُمۡ تُفۡلِحُونَ ١٣٠

O you who have believed, do not consume usury, doubled and multiplied, but fear Allah that you may be successful.

An-Nisā’ 4:161

وَأَخۡذِهِمُ ٱلرِّبَوٰاْ وَقَدۡ نُهُواْ عَنۡهُ وَأَكۡلِهِمۡ أَمۡوَٰلَ ٱلنَّاسِ بِٱلۡبَٰطِلِۚ وَأَعۡتَدۡنَا لِلۡكَٰفِرِينَ مِنۡهُمۡ عَذَابًا أَلِيمٗا ١٦١

And [for] their taking of usury while they had been forbidden from it, and their consuming of the people's wealth unjustly. And we have prepared for the disbelievers among them a painful punishment.

Ar-Rūm 30:39

وَمَآ ءَاتَيۡتُم مِّن رِّبٗا لِّيَرۡبُوَاْ فِيٓ أَمۡوَٰلِ ٱلنَّاسِ فَلَا يَرۡبُواْ عِندَ ٱللَّهِۖ وَمَآ ءَاتَيۡتُم مِّن زَكَوٰةٖ تُرِيدُونَ وَجۡهَ ٱللَّهِ فَأُوْلَٰٓئِكَ هُمُ ٱلۡمُضۡعِفُونَ ٣٩

And whatever you give for interest to increase within the wealth of people will not increase with Allah. But what you give in zakah, desiring the countenance of Allah - those are the multipliers.
