The Last Hour would not come until a person would pass by a grave of another person and he would say: I wish it had been my abode. (Using translation from Muslim 157k)
قَالَ رَسُولُ اللهِ ﷺ لَا تَقُومُ السَّاعَةُ حَتَّى يَمُرَّ الرَّجُلُ بِقَبْرِ الرَّجُلِ فَيَقُولَ يَا لَيْتَنِي مَكَانَهُ مَا بِهِ حُبُّ لِقَاءِ اللهِ
