The answer is ayah 45. This Ayah teaches us when in hardship we must persevere and be patient. When in hardship it's not always a punishment, rather it can be a way of gaining blessing's like in the hadith... Strange are the ways of a believer for there is good in every affair of his and this is not the case with anyone else except in the case of a believer for if he has an occasion to feel delight, he thanks (God), thus there is a good for him in it, and if he gets into trouble and shows resignation (and endures it patiently), there is a good for him in it. Sahih Muslim 2999
