Is there evidence in the hadith that knowledge does not come except through hardship and intensity?

The questioner : Is there evidence in the hadith that knowledge does not come except through hardship and intensity?

The Shaykh : This person is asking, “Is there evidence in the hadith that knowledge does not come except through hardship and intensity?” No, there is no evidence, because this matter is specific to the revelation when it was sent down to the Prophet (peace and blessings be upon him). And your question is considered theft. Why?

The questioner : What is upon him?

The Shaykh : … What is upon him? No, you must not do it again. There is nothing after that. Yes.
