Ṭalāq / divorce: does the Qur'an allow arbitrary, one-sitting final divorce?

وَٱلْمُطَلَّقَـٰتُ يَتَرَبَّصْنَ بِأَنفُسِهِنَّ ثَلَـٰثَةَ قُرُوٓءٍ ۚ وَلَا يَحِلُّ لَهُنَّ أَن يَكْتُمْنَ مَا خَلَقَ ٱللَّهُ فِىٓ أَرْحَامِهِنَّ إِن كُنَّ يُؤْمِنَّ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۚ وَبُعُولَتُهُنَّ أَحَقُّ بِرَدِّهِنَّ فِى ذَٰلِكَ إِنْ أَرَادُوٓا۟ إِصْلَـٰحًا ۚ وَلَهُنَّ مِثْلُ ٱلَّذِى عَلَيْهِنَّ بِٱلْمَعْرُوفِ ۚ وَلِلرِّجَالِ عَلَيْهِنَّ دَرَجَةٌ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌ

Women who are divorced shall wait, keeping themselves apart, three (monthly) courses. And it is not lawful for them that they should conceal that which Allah hath created in their wombs if they are believers in Allah and the Last Day. And their husbands would do better to take them back in that case if they desire a reconciliation. And they (women) have rights similar to those (of men) over them in kindness, and men are a degree above them. Allah is Mighty, Wise.

ٱلطَّلَـٰقُ مَرَّتَانِ ۖ فَإِمْسَاكٌۢ بِمَعْرُوفٍ أَوْ تَسْرِيحٌۢ بِإِحْسَـٰنٍ ۗ وَلَا يَحِلُّ لَكُمْ أَن تَأْخُذُوا۟ مِمَّآ ءَاتَيْتُمُوهُنَّ شَيْـًٔا إِلَّآ أَن يَخَافَآ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ ۖ فَإِنْ خِفْتُمْ أَلَّا يُقِيمَا حُدُودَ ٱللَّهِ فَلَا جُنَاحَ عَلَيْهِمَا فِيمَا ٱفْتَدَتْ بِهِۦ ۗ تِلْكَ حُدُودُ ٱللَّهِ فَلَا تَعْتَدُوهَا ۚ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَأُو۟لَـٰٓئِكَ هُمُ ٱلظَّـٰلِمُونَ

Divorce must be pronounced twice and then (a woman) must be retained in honour or released in kindness. And it is not lawful for you that ye take from women aught of that which ye have given them; except (in the case) when both fear that they may not be able to keep within the limits (imposed by) Allah. And if ye fear that they may not be able to keep the limits of Allah, in that case it is no sin for either of them if the woman ransom herself. These are the limits (imposed by) Allah. Transgress them not. For whoso transgresseth Allah's limits: such are wrong-doers.

فَإِن طَلَّقَهَا فَلَا تَحِلُّ لَهُۥ مِنۢ بَعْدُ حَتَّىٰ تَنكِحَ زَوْجًا غَيْرَهُۥ ۗ فَإِن طَلَّقَهَا فَلَا جُنَاحَ عَلَيْهِمَآ أَن يَتَرَاجَعَآ إِن ظَنَّآ أَن يُقِيمَا حُدُودَ ٱللَّهِ ۗ وَتِلْكَ حُدُودُ ٱللَّهِ يُبَيِّنُهَا لِقَوْمٍ يَعْلَمُونَ

And if he hath divorced her (the third time), then she is not lawful unto him thereafter until she hath wedded another husband. Then if he (the other husband) divorce her it is no sin for both of them that they come together again if they consider that they are able to observe the limits of Allah. These are the limits of Allah. He manifesteth them for people who have knowledge.

وَإِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَبَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ سَرِّحُوهُنَّ بِمَعْرُوفٍ ۚ وَلَا تُمْسِكُوهُنَّ ضِرَارًا لِّتَعْتَدُوا۟ ۚ وَمَن يَفْعَلْ ذَٰلِكَ فَقَدْ ظَلَمَ نَفْسَهُۥ ۚ وَلَا تَتَّخِذُوٓا۟ ءَايَـٰتِ ٱللَّهِ هُزُوًا ۚ وَٱذْكُرُوا۟ نِعْمَتَ ٱللَّهِ عَلَيْكُمْ وَمَآ أَنزَلَ عَلَيْكُم مِّنَ ٱلْكِتَـٰبِ وَٱلْحِكْمَةِ يَعِظُكُم بِهِۦ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ

When ye have divorced women, and they have reached their term, then retain them in kindness or release them in kindness. Retain them not to their hurt so that ye transgress (the limits). He who doeth that hath wronged his soul. Make not the revelations of Allah a laughing-stock (by your behaviour), but remember Allah's grace upon you and that which He hath revealed unto you of the Scripture and of wisdom, whereby He doth exhort you. Observe your duty to Allah and know that Allah is Aware of all things.

وَإِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَن يَنكِحْنَ أَزْوَٰجَهُنَّ إِذَا تَرَٰضَوْا۟ بَيْنَهُم بِٱلْمَعْرُوفِ ۗ ذَٰلِكَ يُوعَظُ بِهِۦ مَن كَانَ مِنكُمْ يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۗ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ ۗ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ

And when ye have divorced women and they reach their term, place not difficulties in the way of their marrying their husbands if it is agreed between them in kindness. This is an admonition for him among you who believeth in Allah and the Last Day. That is more virtuous for you, and cleaner. Allah knoweth; ye know not.

وَإِنْ خِفْتُمْ شِقَاقَ بَيْنِهِمَا فَٱبْعَثُوا۟ حَكَمًا مِّنْ أَهْلِهِۦ وَحَكَمًا مِّنْ أَهْلِهَآ إِن يُرِيدَآ إِصْلَـٰحًا يُوَفِّقِ ٱللَّهُ بَيْنَهُمَآ ۗ إِنَّ ٱللَّهَ كَانَ عَلِيمًا خَبِيرًا

And if ye fear a breach between them twain (the man and wife), appoint an arbiter from his folk and an arbiter from her folk. If they desire amendment Allah will make them of one mind. Lo! Allah is ever Knower, Aware.

يَـٰٓأَيُّهَا ٱلنَّبِىُّ إِذَا طَلَّقْتُمُ ٱلنِّسَآءَ فَطَلِّقُوهُنَّ لِعِدَّتِهِنَّ وَأَحْصُوا۟ ٱلْعِدَّةَ ۖ وَٱتَّقُوا۟ ٱللَّهَ رَبَّكُمْ ۖ لَا تُخْرِجُوهُنَّ مِنۢ بُيُوتِهِنَّ وَلَا يَخْرُجْنَ إِلَّآ أَن يَأْتِينَ بِفَـٰحِشَةٍ مُّبَيِّنَةٍ ۚ وَتِلْكَ حُدُودُ ٱللَّهِ ۚ وَمَن يَتَعَدَّ حُدُودَ ٱللَّهِ فَقَدْ ظَلَمَ نَفْسَهُۥ ۚ لَا تَدْرِى لَعَلَّ ٱللَّهَ يُحْدِثُ بَعْدَ ذَٰلِكَ أَمْرًا

O Prophet! When ye (men) put away women, put them away for their (legal) period and reckon the period, and keep your duty to Allah, your Lord. Expel them not from their houses nor let them go forth unless they commit open immorality. Such are the limits (imposed by) Allah; and whoso transgresseth Allah's limits, he verily wrongeth his soul. Thou knowest not: it may be that Allah will afterward bring some new thing to pass.

فَإِذَا بَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ فَارِقُوهُنَّ بِمَعْرُوفٍ وَأَشْهِدُوا۟ ذَوَىْ عَدْلٍ مِّنكُمْ وَأَقِيمُوا۟ ٱلشَّهَـٰدَةَ لِلَّهِ ۚ ذَٰلِكُمْ يُوعَظُ بِهِۦ مَن كَانَ يُؤْمِنُ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۚ وَمَن يَتَّقِ ٱللَّهَ يَجْعَل لَّهُۥ مَخْرَجًا

Then, when they have reached their term, take them back in kindness or part from them in kindness, and call to witness two just men among you, and keep your testimony upright for Allah. Whoso believeth in Allah and the Last Day is exhorted to act thus. And whosoever keepeth his duty to Allah, Allah will appoint a way out for him,
