What does the Quran say about trials?

أَمْ حَسِبْتُمْ أَن تَدْخُلُوا۟ ٱلْجَنَّةَ وَلَمَّا يَأْتِكُم مَّثَلُ ٱلَّذِينَ خَلَوْا۟ مِن قَبْلِكُم ۖ مَّسَّتْهُمُ ٱلْبَأْسَآءُ وَٱلضَّرَّآءُ وَزُلْزِلُوا۟ حَتَّىٰ يَقُولَ ٱلرَّسُولُ وَٱلَّذِينَ ءَامَنُوا۟ مَعَهُۥ مَتَىٰ نَصْرُ ٱللَّهِ ۗ أَلَآ إِنَّ نَصْرَ ٱللَّهِ قَرِيبٌۭ

Or do you think that you will enter Paradise while such [trial] has not yet come to you as came to those who passed on before you? They were touched by poverty and hardship and were shaken until [even their] messenger and those who believed with him said, "When is the help of Allah?" Unquestionably, the help of Allah is near.

وَٱعْلَمُوٓا۟ أَنَّمَآ أَمْوَٰلُكُمْ وَأَوْلَٰدُكُمْ فِتْنَةٌۭ وَأَنَّ ٱللَّهَ عِندَهُۥٓ أَجْرٌ عَظِيمٌۭ

And know that your properties and your children are but a trial and that Allah has with Him a great reward.

قُل لَّن يُصِيبَنَآ إِلَّا مَا كَتَبَ ٱللَّهُ لَنَا هُوَ مَوْلَىٰنَا ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

Say, "Never will we be struck except by what Allah has decreed for us; He is our protector." And upon Allah let the believers rely.

وَلَئِنْ أَذَقْنَا ٱلْإِنسَٰنَ مِنَّا رَحْمَةًۭ ثُمَّ نَزَعْنَٰهَا مِنْهُ إِنَّهُۥ لَيَـُٔوسٌۭ كَفُورٌۭ

And if We give man a taste of mercy from Us and then We withdraw it from him, indeed, he is despairing and ungrateful.

وَلَئِنْ أَذَقْنَٰهُ نَعْمَآءَ بَعْدَ ضَرَّآءَ مَسَّتْهُ لَيَقُولَنَّ ذَهَبَ ٱلسَّيِّـَٔاتُ عَنِّىٓ ۚ إِنَّهُۥ لَفَرِحٌۭ فَخُورٌ

But if We give him a taste of favor after hardship has touched him, he will surely say, "Bad times have left me." Indeed, he is exultant and boastful -

إِلَّا ٱلَّذِينَ صَبَرُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ أُو۟لَٰٓئِكَ لَهُم مَّغْفِرَةٌۭ وَأَجْرٌۭ كَبِيرٌۭ

Except for those who are patient and do righteous deeds; those will have forgiveness and great reward.

كُلُّ نَفْسٍۢ ذَآئِقَةُ ٱلْمَوْتِ ۗ وَنَبْلُوكُم بِٱلشَّرِّ وَٱلْخَيْرِ فِتْنَةًۭ ۖ وَإِلَيْنَا تُرْجَعُونَ

Every soul will taste death. And We test you with evil and with good as trial; and to Us you will be returned.

أَحَسِبَ ٱلنَّاسُ أَن يُتْرَكُوٓا۟ أَن يَقُولُوٓا۟ ءَامَنَّا وَهُمْ لَا يُفْتَنُونَ

Do the people think that they will be left to say, "We believe" and they will not be tried?

وَلَقَدْ فَتَنَّا ٱلَّذِينَ مِن قَبْلِهِمْ ۖ فَلَيَعْلَمَنَّ ٱللَّهُ ٱلَّذِينَ صَدَقُوا۟ وَلَيَعْلَمَنَّ ٱلْكَٰذِبِينَ

But We have certainly tried those before them, and Allah will surely make evident those who are truthful, and He will surely make evident the liars.

فَإِذَا مَسَّ ٱلْإِنسَٰنَ ضُرٌّۭ دَعَانَا ثُمَّ إِذَا خَوَّلْنَٰهُ نِعْمَةًۭ مِّنَّا قَالَ إِنَّمَآ أُوتِيتُهُۥ عَلَىٰ عِلْمٍۭ ۚ بَلْ هِىَ فِتْنَةٌۭ وَلَٰكِنَّ أَكْثَرَهُمْ لَا يَعْلَمُونَ

And when adversity touches man, he calls upon Us; then when We bestow on him a favor from Us, he says, "I have only been given it because of [my] knowledge." Rather, it is a trial, but most of them do not know.

مَآ أَصَابَ مِن مُّصِيبَةٍۢ فِى ٱلْأَرْضِ وَلَا فِىٓ أَنفُسِكُمْ إِلَّا فِى كِتَٰبٍۢ مِّن قَبْلِ أَن نَّبْرَأَهَآ ۚ إِنَّ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٌۭ

No disaster strikes upon the earth or among yourselves except that it is in a register before We bring it into being - indeed that, for Allah, is easy -

لِّكَيْلَا تَأْسَوْا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا تَفْرَحُوا۟ بِمَآ ءَاتَىٰكُمْ ۗ وَٱللَّهُ لَا يُحِبُّ كُلَّ مُخْتَالٍۢ فَخُورٍ

In order that you not despair over what has eluded you and not exult [in pride] over what He has given you. And Allah does not like everyone self-deluded and boastful -

مَآ أَصَابَ مِن مُّصِيبَةٍ إِلَّا بِإِذْنِ ٱللَّهِ ۗ وَمَن يُؤْمِنۢ بِٱللَّهِ يَهْدِ قَلْبَهُۥ ۚ وَٱللَّهُ بِكُلِّ شَىْءٍ عَلِيمٌۭ

No disaster strikes except by permission of Allah. And whoever believes in Allah - He will guide his heart. And Allah is Knowing of all things.

إِنَّمَآ أَمْوَٰلُكُمْ وَأَوْلَٰدُكُمْ فِتْنَةٌۭ ۚ وَٱللَّهُ عِندَهُۥٓ أَجْرٌ عَظِيمٌۭ

Your wealth and your children are but a trial, and Allah has with Him a great reward.

لِيُنفِقْ ذُو سَعَةٍۢ مِّن سَعَتِهِۦ ۖ وَمَن قُدِرَ عَلَيْهِ رِزْقُهُۥ فَلْيُنفِقْ مِمَّآ ءَاتَىٰهُ ٱللَّهُ ۚ لَا يُكَلِّفُ ٱللَّهُ نَفْسًا إِلَّا مَآ ءَاتَىٰهَا ۚ سَيَجْعَلُ ٱللَّهُ بَعْدَ عُسْرٍۢ يُسْرًۭا

Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allah has given him. Allah does not charge a soul except [according to] what He has given it. Allah will bring about, after hardship, ease.

ٱلَّذِى خَلَقَ ٱلْمَوْتَ وَٱلْحَيَوٰةَ لِيَبْلُوَكُمْ أَيُّكُمْ أَحْسَنُ عَمَلًۭا ۚ وَهُوَ ٱلْعَزِيزُ ٱلْغَفُورُ

[He] who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving -

۞ إِنَّ ٱلْإِنسَٰنَ خُلِقَ هَلُوعًا

Indeed, mankind was created anxious:

إِذَا مَسَّهُ ٱلشَّرُّ جَزُوعًۭا

When evil touches him, impatient,

وَإِذَا مَسَّهُ ٱلْخَيْرُ مَنُوعًا

And when good touches him, withholding [of it],

فَأَمَّا ٱلْإِنسَٰنُ إِذَا مَا ٱبْتَلَىٰهُ رَبُّهُۥ فَأَكْرَمَهُۥ وَنَعَّمَهُۥ فَيَقُولُ رَبِّىٓ أَكْرَمَنِ

And as for man, when his Lord tries him and [thus] is generous to him and favors him, he says, "My Lord has honored me."

وَأَمَّآ إِذَا مَا ٱبْتَلَىٰهُ فَقَدَرَ عَلَيْهِ رِزْقَهُۥ فَيَقُولُ رَبِّىٓ أَهَٰنَنِ

But when He tries him and restricts his provision, he says, "My Lord has humiliated me."

لَقَدْ خَلَقْنَا ٱلْإِنسَٰنَ فِى كَبَدٍ

We have certainly created man into hardship.
