The Messenger of Allah ﷺ happened to pass by two graves and said: They (their occupants) are being tormented, but they are not tormented for a grievous sin. One of them carried tales and the other did not keep himself safe from being defiled by urine. He then called for a fresh twig and split it into two parts, and planted them on each grave and then said: Perhaps, their punishment way be mitigated as long as these twigs remain fresh.  

مَرَّ رَسُولُ اللَّهِ ﷺ عَلَى قَبْرَيْنِ فَقَالَ أَمَا إِنَّهُمَا لَيُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا أَحَدُهُمَا فَكَانَ يَمْشِي بِالنَّمِيمَةِ وَأَمَّا الآخَرُ فَكَانَ لاَ يَسْتَتِرُ مِنْ بَوْلِهِ قَالَ فَدَعَا بِعَسِيبٍ رَطْبٍ فَشَقَّهُ بِاثْنَيْنِ ثُمَّ غَرَسَ عَلَى هَذَا وَاحِدًا وَعَلَى هَذَا وَاحِدًا ثُمَّ قَالَ لَعَلَّهُ أَنْ يُخَفَّفَ عَنْهُمَا مَا لَمْ يَيْبَسَا  

" The other did not keep himself safe from being defiled by urine."  

أَنَّهُ قَالَ وَكَانَ الآخَرُ لاَ يَسْتَنْزِهُ عَنِ الْبَوْلِ أَوْ مِنَ الْبَوْلِ
