Ibn Abbas reported:
وَ حَدَّثَنَا أَبُو سَعِيدٍ الأَشَجُّ ، وَأَبُو كُرَيْبٍ مُحَمَّدُ بْنُ الْعَلاَءِ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا وَكِيعٌ ، حَدَّثَنَا الأَعْمَشُ ، قَالَ سَمِعْتُ مُجَاهِدًا ، يُحَدِّثُ عَنْ طَاوُسٍ ، عَنِ ابْنِ عَبَّاسٍ ، قَالَ مَرَّ رَسُولُ اللَّهِ صلى الله عليه وسلم 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 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.
