2. 2:275Al-Baqarah
   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 فَأُوْلَـٰٓئِكَ أَصۡحَٰبُ ٱلنَّارِۖ هُمۡ فِيهَا خَٰلِدُونَ
   Those who swallow usury cannot rise up save as he ariseth whom the devil hath prostrated by (his) touch. That is because they say: Trade is just like usury; whereas Allah permitteth trading and forbiddeth usury. He unto whom an admonition from his Lord cometh, and (he) refraineth (in obedience thereto), he shall keep (the profits of) that which is past, and his affair (henceforth) is with Allah. As for him who returneth (to usury) - Such are rightful owners of the Fire. They will abide therein.
   In context

   Those who take interest will rise from their graves on the Day of Resurrection like a person who is afflicted by Satan: they will stand up from their graves and then fall like a person who is epileptic. This is because they made usury permissible and made no distinction between usury and that which Allah has permitted in terms of profit earned through sales transactions.

   Tell My bondmen who believe to establish worship and spend of that which We have given them, secretly and publicly, before a day cometh wherein there will be neither traffick nor befriending.

4. 24:37An-NurWarning
   رِجَالٞ لَّا تُلۡهِيهِمۡ تِجَٰرَةٞ وَلَا بَيۡعٌ عَن ذِكۡرِ ٱللَّهِ وَإِقَامِ ٱلصَّلَوٰةِ وَإِيتَآءِ ٱلزَّكَوٰةِ يَخَافُونَ يَوۡمٗا تَتَقَلَّبُ فِيهِ ٱلۡقُلُوبُ وَٱلۡأَبۡصَٰرُ

   In context

   Men whom buying and selling does not distract from the remembrance of Allah, performing prayer with perfection and giving Zakat, where required.
