What is patience (ṣabr) in the Qur'an?

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱسْتَعِينُوا۟ بِٱلصَّبْرِ وَٱلصَّلَوٰةِ ۚ إِنَّ ٱللَّهَ مَعَ ٱلصَّـٰبِرِينَ

O ye who believe! Seek help in steadfastness and prayer. Lo! Allah is with the steadfast.

وَلَنَبْلُوَنَّكُم بِشَىْءٍ مِّنَ ٱلْخَوْفِ وَٱلْجُوعِ وَنَقْصٍ مِّنَ ٱلْأَمْوَٰلِ وَٱلْأَنفُسِ وَٱلثَّمَرَٰتِ ۗ وَبَشِّرِ ٱلصَّـٰبِرِينَ

And surely We shall try you with something of fear and hunger, and loss of wealth and lives and crops; but give glad tidings to the steadfast,

ٱلَّذِينَ إِذَآ أَصَـٰبَتْهُم مُّصِيبَةٌ قَالُوٓا۟ إِنَّا لِلَّهِ وَإِنَّآ إِلَيْهِ رَٰجِعُونَ

Who say, when a misfortune striketh them: Lo! we are Allah's and lo! unto Him we are returning.

أُو۟لَـٰٓئِكَ عَلَيْهِمْ صَلَوَٰتٌ مِّن رَّبِّهِمْ وَرَحْمَةٌ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُهْتَدُونَ

Such are they on whom are blessings from their Lord, and mercy. Such are the rightly guided.

قُلْ يَـٰعِبَادِ ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ رَبَّكُمْ ۚ لِلَّذِينَ أَحْسَنُوا۟ فِى هَـٰذِهِ ٱلدُّنْيَا حَسَنَةٌ ۗ وَأَرْضُ ٱللَّهِ وَٰسِعَةٌ ۗ إِنَّمَا يُوَفَّى ٱلصَّـٰبِرُونَ أَجْرَهُم بِغَيْرِ حِسَابٍ

Say: O My bondmen who believe! Observe your duty to your Lord. For those who do good in this world there is good, and Allah's earth is spacious. Verily the steadfast will be paid their wages without stint.

إِلَّا ٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ وَتَوَاصَوْا۟ بِٱلْحَقِّ وَتَوَاصَوْا۟ بِٱلصَّبْرِ

Save those who believe and do good works, and exhort one another to truth and exhort one another to endurance.
