Riyad as-Salihin, Book 19, Hadith 1821 (In-Book) ⓘ

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah said, "By Him in Whose Hand my soul is, the world will not come to an end until a man passes by a grave and will lie over it saying, 'Would that I were in this grave (i.e., dead)!' Not he will say so because of religious reasons but because of widespread mischief and severe trials of this world."[Al-Bukhari and Muslim].

وعنه رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم ‏:‏ ‏ "‏ والذي نفسي بيده لا تذهب الدنيا حتى يمر الرجل بالقبر، فيتمرغ عليه، ويقول‏:‏ ياليتني مكان صاحب هذا القبر، وليس به الدين، ما به إلا البلاء‏" ‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
