"The Prophet passed by two graves. He said: 'These two are being punished. And they are not being punished for something major. As for this one, he would not protect himself from his urine. As for this one, he used to spread Namimah (slander).'"  

أَنَّ النَّبِيَّ ﷺ مَرَّ عَلَى قَبْرَيْنِ فَقَالَ إِنَّهُمَا يُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا هَذَا فَكَانَ لاَ يَسْتَتِرُ مِنْ بَوْلِهِ وَأَمَّا هَذَا فَكَانَ يَمْشِي بِالنَّمِيمَةِ
