The Messenger of Allah ﷺ said, "By the One in whose hand my soul rests, this world will not pass away until a man will walk past a grave, throw himself upon it, and say, 'I wish I were in the place of the one buried in this grave,' and it will not be religion that drives him to this, but only the severity of his trials."
قال رسول الله ﷺ: والذي نفسي بيده لا تذهب الدنيا حتى يمر الرجل على القبر، فيتمرغ عليه، ويقول: يا ليتني كنت مكان صاحب هذا القبر، وليس به الدين إلا البلاء.
