1. 4:140 وَقَدْ نَزَّلَ عَلَيْكُمْ فِى ٱلْكِتَٰبِ أَنْ إِذَا سَمِعْتُمْ ءَايَٰتِ ٱللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلَا تَقْعُدُوا۟ مَعَهُمْ حَتَّىٰ يَخُوضُوا۟ فِى حَدِيثٍ غَيْرِهِۦٓ إِنَّكُمْ إِذًا مِّثْلُهُمْ إِنَّ ٱللَّهَ جَامِعُ ٱلْمُنَٰفِقِينَ وَٱلْكَٰفِرِينَ فِى جَهَنَّمَ جَمِيعًا

   And indeed He has revealed to you in the Book that when you hear Allah's communications disbelieved in and mocked at do not sit with them until they enter into some other discourse; surely then you would be like them; surely Allah will gather together the hypocrites and the unbelievers all in hell.
   

2. 6:68 وَإِذَا رَأَيْتَ ٱلَّذِينَ يَخُوضُونَ فِىٓ ءَايَٰتِنَا فَأَعْرِضْ عَنْهُمْ حَتَّىٰ يَخُوضُوا۟ فِى حَدِيثٍ غَيْرِهِۦ وَإِمَّا يُنسِيَنَّكَ ٱلشَّيْطَٰنُ فَلَا تَقْعُدْ بَعْدَ ٱلذِّكْرَىٰ مَعَ ٱلْقَوْمِ ٱلظَّٰلِمِينَ

   And when you see those who enter into false discourses about Our communications, withdraw from them until they enter into some other discourse, and if the Shaitan causes you to forget, then do not sit after recollection with the unjust people.
   

3. 6:91 وَمَا قَدَرُوا۟ ٱللَّهَ حَقَّ قَدْرِهِۦٓ إِذْ قَالُوا۟ مَآ أَنزَلَ ٱللَّهُ عَلَىٰ بَشَرٍ مِّن شَىْءٍ قُلْ مَنْ أَنزَلَ ٱلْكِتَٰبَ ٱلَّذِى جَآءَ بِهِۦ مُوسَىٰ نُورًا وَهُدًى لِّلنَّاسِ تَجْعَلُونَهُۥ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًا وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوٓا۟ أَنتُمْ وَلَآ ءَابَآؤُكُمْ قُلِ ٱللَّهُ ثُمَّ ذَرْهُمْ فِى خَوْضِهِمْ يَلْعَبُونَ

   And they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much? And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses.
   

4. 9:65 وَلَئِن سَأَلْتَهُمْ لَيَقُولُنَّ إِنَّمَا كُنَّا نَخُوضُ وَنَلْعَبُ قُلْ أَبِٱللَّهِ وَءَايَٰتِهِۦ وَرَسُولِهِۦ كُنتُمْ تَسْتَهْزِءُونَ

   And if you should question them, they would certainly say: We were only idly discoursing and sporting. Say: Was it at Allah and His communications and His Messenger that you mocked?
   

5. 9:69 كَٱلَّذِينَ مِن قَبْلِكُمْ كَانُوٓا۟ أَشَدَّ مِنكُمْ قُوَّةً وَأَكْثَرَ أَمْوَٰلًا وَأَوْلَٰدًا فَٱسْتَمْتَعُوا۟ بِخَلَٰقِهِمْ فَٱسْتَمْتَعْتُم بِخَلَٰقِكُمْ كَمَا ٱسْتَمْتَعَ ٱلَّذِينَ مِن قَبْلِكُم بِخَلَٰقِهِمْ وَخُضْتُمْ كَٱلَّذِى خَاضُوٓا۟ أُو۟لَٰٓئِكَ حَبِطَتْ أَعْمَٰلُهُمْ فِى ٱلدُّنْيَا وَٱلْءَاخِرَةِ وَأُو۟لَٰٓئِكَ هُمُ ٱلْخَٰسِرُونَ

   Like those before you; they were stronger than you in power and more abundant in wealth and children, so they enjoyed their portion; thus have you enjoyed your portion as those before you enjoyed their portion; and you entered into vain discourses like the vain discourses in which entered those before you. These are they whose works are null in this world and the hereafter, and these are they who are the losers.
   

6. 43:83 فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ

   So leave them plunging into false discourses and sporting until they meet their day which they are threatened with.
   

7. 52:12 ٱلَّذِينَ هُمْ فِى خَوْضٍ يَلْعَبُونَ

   Those who sport entering into vain discourses.
   

8. 70:42 فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ

   Therefore leave them alone to go on with the false discourses and to sport until they come face to face with that day of theirs with which they are threatened;
   

9. 74:45 وَكُنَّا نَخُوضُ مَعَ ٱلْخَآئِضِينَ

   And we used to enter into vain discourse with those who entered into vain discourses.
