The root ع ز م (ʿ-z-m) in the Quran

وَإِنْ عَزَمُوا۟ ٱلطَّلَٰقَ فَإِنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌ ۝٢٢٧

And if they decide on divorce - then indeed, Allāh is Hearing and Knowing.

وَلَا جُنَاحَ عَلَيْكُمْ فِيمَا عَرَّضْتُم بِهِۦ مِنْ خِطْبَةِ ٱلنِّسَآءِ أَوْ أَكْنَنتُمْ فِىٓ أَنفُسِكُمْ عَلِمَ ٱللَّهُ أَنَّكُمْ سَتَذْكُرُونَهُنَّ وَلَٰكِن لَّا تُوَاعِدُوهُنَّ سِرًّا إِلَّآ أَن تَقُولُوا۟ قَوْلًا مَّعْرُوفًا وَلَا تَعْزِمُوا۟ عُقْدَةَ ٱلنِّكَاحِ حَتَّىٰ يَبْلُغَ ٱلْكِتَٰبُ أَجَلَهُۥ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ يَعْلَمُ مَا فِىٓ أَنفُسِكُمْ فَٱحْذَرُوهُ وَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ غَفُورٌ حَلِيمٌ ۝٢٣٥

There is no blame upon you for that to which you [indirectly] allude concerning a proposal to women or for what you conceal within yourselves. Allāh knows that you will have them in mind. But do not promise them secretly except for saying a proper saying. And do not determine to undertake a marriage contract until the decreed period reaches its end. And know that Allāh knows what is within yourselves, so beware of Him. And know that Allāh is Forgiving and Forbearing.

فَبِمَا رَحْمَةٍ مِّنَ ٱللَّهِ لِنتَ لَهُمْ وَلَوْ كُنتَ فَظًّا غَلِيظَ ٱلْقَلْبِ لَٱنفَضُّوا۟ مِنْ حَوْلِكَ فَٱعْفُ عَنْهُمْ وَٱسْتَغْفِرْ لَهُمْ وَشَاوِرْهُمْ فِى ٱلْأَمْرِ فَإِذَا عَزَمْتَ فَتَوَكَّلْ عَلَى ٱللَّهِ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَوَكِّلِينَ ۝١٥٩

So by mercy from Allāh, [O Muḥammad], you were lenient with them. And if you had been rude [in speech] and harsh in heart, they would have disbanded from about you. So pardon them and ask forgiveness for them and consult them in the matter. And when you have decided, then rely upon Allāh. Indeed, Allāh loves those who rely [upon Him].

لَتُبْلَوُنَّ فِىٓ أَمْوَٰلِكُمْ وَأَنفُسِكُمْ وَلَتَسْمَعُنَّ مِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ مِن قَبْلِكُمْ وَمِنَ ٱلَّذِينَ أَشْرَكُوٓا۟ أَذًى كَثِيرًا وَإِن تَصْبِرُوا۟ وَتَتَّقُوا۟ فَإِنَّ ذَٰلِكَ مِنْ عَزْمِ ٱلْأُمُورِ ۝١٨٦

You will surely be tested in your possessions and in yourselves. And you will surely hear from those who were given the Scripture before you and from those who associate others with Allāh much abuse. But if you are patient and fear Allāh - indeed, that is of the matters [worthy] of resolve.

وَلَقَدْ عَهِدْنَآ إِلَىٰٓ ءَادَمَ مِن قَبْلُ فَنَسِىَ وَلَمْ نَجِدْ لَهُۥ عَزْمًا ۝١١٥

And We had already taken a promise from Adam before, but he forgot; and We found not in him determination.

يَٰبُنَىَّ أَقِمِ ٱلصَّلَوٰةَ وَأْمُرْ بِٱلْمَعْرُوفِ وَٱنْهَ عَنِ ٱلْمُنكَرِ وَٱصْبِرْ عَلَىٰ مَآ أَصَابَكَ إِنَّ ذَٰلِكَ مِنْ عَزْمِ ٱلْأُمُورِ ۝١٧

O my son, establish prayer, enjoin what is right, forbid what is wrong, and be patient over what befalls you. Indeed, [all] that is of the matters [requiring] resolve.

وَلَمَن صَبَرَ وَغَفَرَ إِنَّ ذَٰلِكَ لَمِنْ عَزْمِ ٱلْأُمُورِ ۝٤٣

And whoever is patient and forgives - indeed, that is of the matters [worthy] of resolve.

فَٱصْبِرْ كَمَا صَبَرَ أُو۟لُوا۟ ٱلْعَزْمِ مِنَ ٱلرُّسُلِ وَلَا تَسْتَعْجِل لَّهُمْ كَأَنَّهُمْ يَوْمَ يَرَوْنَ مَا يُوعَدُونَ لَمْ يَلْبَثُوٓا۟ إِلَّا سَاعَةً مِّن نَّهَارٍۭ بَلَٰغٌ فَهَلْ يُهْلَكُ إِلَّا ٱلْقَوْمُ ٱلْفَٰسِقُونَ ۝٣٥

So be patient, [O Muḥammad], as were those of determination among the messengers and do not be impatient for them. It will be - on the Day they see that which they are promised - as though they had not remained [in the world] except an hour of a day. [This is] notification. And will [any] be destroyed except the defiantly disobedient people?

طَاعَةٌ وَقَوْلٌ مَّعْرُوفٌ فَإِذَا عَزَمَ ٱلْأَمْرُ فَلَوْ صَدَقُوا۟ ٱللَّهَ لَكَانَ خَيْرًا لَّهُمْ ۝٢١

Obedience and good words. And when the matter [of fighting] was determined, if they had been true to Allāh, it would have been better for them.
