The Quran root خ و ض kh-w-ḍ

وَقَدْ نَزَّلَ عَلَيْكُمْ فِي الْكِتَابِ أَنْ إِذَا سَمِعْتُمْ آيَاتِ اللَّهِ يُكْفَرُ بِهَا وَيُسْتَهْزَأُ بِهَا فَلَا تَقْعُدُوا مَعَهُمْ حَتَّىٰ يَخُوضُوا فِي حَدِيثٍ غَيْرِهِ إِنَّكُمْ إِذًا مِّثْلُهُمْ إِنَّ اللَّهَ جَامِعُ الْمُنَافِقِينَ وَالْكَافِرِينَ فِي جَهَنَّمَ جَمِيعًا ١٤٠

يَخُوضُوا yakhūḍū · they engage

And it has already come down to you in the Book [i.e., the Qur’ān] that when you hear the verses of Allāh [recited], they are denied [by them] and ridiculed; so do not sit with them until they enter into another conversation. Indeed, you would then be like them. Indeed, Allāh will gather the hypocrites and disbelievers in Hell all together - (Surah An-Nisa, 4:140)

وَإِذَا رَأَيْتَ الَّذِينَ يَخُوضُونَ فِي آيَاتِنَا فَأَعْرِضْ عَنْهُمْ حَتَّىٰ يَخُوضُوا فِي حَدِيثٍ غَيْرِهِ وَإِمَّا يُنسِيَنَّكَ الشَّيْطَانُ فَلَا تَقْعُدْ بَعْدَ الذِّكْرَىٰ مَعَ الْقَوْمِ الظَّالِمِينَ ٦٨

يَخُوضُونَ yakhūḍūna · engage (in vain talks)

And when you see those who engage in [offensive] discourse concerning Our verses, then turn away from them until they enter into another conversation. And if Satan should cause you to forget, then do not remain after the reminder with the wrongdoing people. (Surah Al-An'am, 6:68)

وَمَا قَدَرُوا اللَّهَ حَقَّ قَدْرِهِ إِذْ قَالُوا مَا أَنزَلَ اللَّهُ عَلَىٰ بَشَرٍ مِّن شَيْءٍ قُلْ مَنْ أَنزَلَ الْكِتَابَ الَّذِي جَاءَ بِهِ مُوسَىٰ نُورًا وَهُدًى لِّلنَّاسِ تَجْعَلُونَهُ قَرَاطِيسَ تُبْدُونَهَا وَتُخْفُونَ كَثِيرًا وَعُلِّمْتُم مَّا لَمْ تَعْلَمُوا أَنتُمْ وَلَا آبَاؤُكُمْ قُلِ اللَّهُ ثُمَّ ذَرْهُمْ فِي خَوْضِهِمْ يَلْعَبُونَ ٩١

خَوْضِهِمْ khawḍihim · their discourse

And they did not appraise Allāh with true appraisal when they said, "Allāh did not reveal to a human being anything." Say, "Who revealed the Scripture that Moses brought as light and guidance to the people? You [Jews] make it into pages, disclosing [some of] it and concealing much. And you were taught that which you knew not - neither you nor your fathers." Say, "Allāh [revealed it]." Then leave them in their [empty] discourse, amusing themselves. (Surah Al-An'am, 6:91)

وَكُنَّا نَخُوضُ مَعَ الْخَائِضِينَ ٤٥

الْخَائِضِينَ l-khāiḍīna · the vain talkers

And we used to enter into vain discourse with those who engaged [in it], (Surah Al-Muddaththir, 74:45)
