Abu Bakrah reported: The Prophet, peace and blessings be upon him, passed by two graves and he said, “Verily, they are both being punished, but not for a sin difficult to avoid. As for one, he is punished for the habit of soiling himself with urine. As for the other, he is punished for the habit of backbiting.”

عَنْ أَبِي بَكْرَةَ قَالَ قَالَ مَرَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِقَبْرَيْنِ فَقَالَ إِنَّهُمَا لَيُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا أَحَدُهُمَا فَيُعَذَّبُ فِي الْبَوْلِ وَأَمَّا الْآخَرُ فَيُعَذَّبُ فِي الْغَيْبَةِ
