Hardship is mentioned in the Quran in these verses:
[2:177] Righteousness is not turning your faces towards the east or the west. Righteous are those who believe in God, the Last Day, the angels, the scripture, and the prophets; and they give the money, cheerfully, to the relatives, the orphans, the needy, the traveling alien, the beggars, and to free the slaves; and they observe the Contact Prayers (Salat) and give the obligatory charity (Zakat); and they keep their word whenever they make a promise; and they steadfastly persevere in the face of persecution, hardship, and war. These are the truthful; these are the righteous.
[2:185] Ramadan is the month during which the Quran was revealed, providing guidance for the people, clear teachings, and the statute book. Those of you who witness this month shall fast therein. Those who are ill or traveling may substitute the same number of other days. God wishes for you convenience, not hardship, that you may fulfill your obligations, and to glorify God for guiding you, and to express your appreciation.
[2:214] Do you expect to enter Paradise without being tested like those before you? They were tested with hardship and adversity, and were shaken up, until the messenger and those who believed with him said, “Where is God’s victory?” God’s victory is near.
[3:108] These are God’s revelations; we recite them to you, truthfully. God does not wish any hardship for the people.
[3:140] If you suffer hardship, the enemy also suffers the same hardship. We alternate the days of victory and defeat among the people. God thus distinguishes the true believers, and blesses some of you with martyrdom. God dislikes injustice.
[3:153] Recall that you rushed (after the spoils), paying no attention to anyone, even when the messenger was calling from behind you. Consequently, He substituted one misery for another, that you may not grieve over anything you had missed, or agonize over any hardship you had suffered. God is Cognizant of everything you do.
[4:3] If you deem it best for the orphans, you may marry their mothers – you may marry two, three, or four. If you fear lest you become unfair, then you shall be content with only one, or with what you already have. Additionally, you are thus more likely to avoid financial hardship.
[6:42] We have sent (messengers) to communities before you, and we put them to the test through adversity and hardship, that they may implore.
[7:94] Whenever we sent a prophet to any community, we afflicted its people with adversity and hardship, that they may implore.
[7:95] Then we substituted peace and prosperity in place of that hardship. But alas, they turned heedless and said, “It was our parents who experienced that hardship before prosperity.” Consequently, we punished them suddenly when they least expected.
[7:131] When good omens came their way, they said, “We have deserved this,” but when a hardship afflicted them, they blamed Moses and those with him. In fact, their omens are decided only by God, but most of them do not know.
[7:168] We scattered them among many communities throughout the land. Some of them were righteous, and some were less than righteous. We tested them with prosperity and hardship, that they may return.
[9:49] Some of them would say, “Give me permission (to stay behind); do not impose such a hardship on me.” In fact, they have thus incurred a terrible hardship; Hell is surrounding the disbelievers.
[9:120] Neither the dwellers of the city, nor the Arabs around them, shall seek to stay behind the messenger of God (when he mobilizes for war). Nor shall they give priority to their own affairs over supporting him. This is because they do not suffer any thirst, or any effort, or hunger in the cause of God, or take a single step that enrages the disbelievers, or inflict any hardship upon the enemy, without having it written down for them as a credit. God never fails to recompense those who work righteousness.
[10:12] When adversity touches the human being, he implores us while lying down, or sitting, or standing up. But as soon as we relieve his adversity, he goes on as if he never implored us to relieve any hardship! The works of the transgressors are thus adorned in their eyes.
[10:107] If God touches you with a hardship, none can relieve it except He. And when He blesses you, no force can prevent His grace. He bestows it upon whomever He chooses from among His servants. He is the Forgiver, Most Merciful.
[12:88] When they entered (Joseph’s) quarters, they said, “O you noble one, we have suffered a lot of hardship, along with our family, and we have brought inferior goods. But we hope that you will give us full measure and be charitable to us. God rewards the charitable.”
[13:11] Shifts (of angels) take turns, staying with each one of you – they are in front of you and behind you. They stay with you, and guard you in accordance with God’s commands. Thus, God does not change the condition of any people unless they themselves make the decision to change. If God wills any hardship for any people, no force can stop it. For they have none beside Him as Lord and Master.
[16:7] And they carry your loads to lands that you could not reach without a great hardship. Surely, your Lord is Compassionate, Most Merciful.
[16:112] God cites the example of a community that used to be secure and prosperous, with provisions coming to it from everywhere. But then, it turned unappreciative of God’s blessings. Consequently, God caused them to taste the hardships of starvation and insecurity. Such is the requital for what they did.
[20:2] We did not reveal the Quran to you, to cause you any hardship.
[22:78] You shall strive for the cause of God as you should strive for His cause. He has chosen you and has placed no hardship on you in practicing your religion – the religion of your father Abraham. He is the one who named you “Submitters” originally. Thus, the messenger shall serve as a witness among you, and you shall serve as witnesses among the people. Therefore, you shall observe the Contact Prayers (Salat) and give the obligatory charity (Zakat), and hold fast to God; He is your Lord, the best Lord and the best Supporter.
[29:10] Among the people there are those who say, “We believe in God,” but as soon as they suffer any hardship because of God, they equate the people’s persecution with God’s retribution. But if blessings from your Lord come your way, they say, “We were with you.” Is God not fully aware of the people’s innermost thoughts?
[38:41] Remember our servant Job: he called upon his Lord, “The devil has afflicted me with hardship and pain.”
[47:37] If He asked you for money, to the extent of creating a hardship for you, you might have become stingy, and your hidden evil might be exposed.
[90:12] Which one is the difficult path?
[90:13] The freeing of slaves.
[90:14] Feeding, during the time of hardship.
