Combining the fact that calamities are a punishment with the testing of the prophets and the righteous

Question:
May Allah reward you. Honorable Shaykh, this questioner says: What is the reconciliation between the saying of Allah the Exalted, , and the saying of the Prophet (peace and blessings be upon him), "The most severely tested of people are the prophets," and also his saying, "A servant is tested according to the measure of his faith"?

Answer:
Yes, a person may be struck by calamities as a punishment for his sins, to purify him. He may also be struck by calamities so that Allah raises his ranks in Paradise. He is struck without any sins so that Allah raises his ranks, because Allah has written for him a rank in Paradise that he will not attain through his deeds, so He strikes him with calamities so that he is patient and seeks reward, and Allah raises him in Paradise.
