It was narrated that Ibn 'Abbas said: "The Messenger of Allah (s.a.w) passed by two graves, and he said: 'They are being punished, but they are not being punished for anything grave (i.e., it was not difficult to avoid). One of them used to walk around spreading malicious gossip, and the other did not protect himself from his urine.' He (s.a.w) called for a palm branch, split it in two, then planted one piece on one grave and the other on the other grave. Then he said: 'Perhaps it (the punishment) will be reduced for them so long as this does not dry out."'

حَدَّثَنِي أَبُو سَعِيدٍ الْأَشَجُّ وَأَبُو كُرَيْبٍ مُحَمَّدُ بْنُ الْعَلَاءِ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ الْآخَرَانِ حَدَّثَنَا وَكِيعٌ حَدَّثَنَا الْأَعْمَشُ قَالَ سَمِعْتُ مُجَاهِدًا يُحَدِّثُ عَنْ طَاوُسٍ عَنْ ابْنِ عَبَّاسٍ قَالَ مَرَّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى قَبْرَيْنِ فَقَالَ أَمَا إِنَّهُمَا لَيُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا أَحَدُهُمَا فَكَانَ يَمْشِي بِالنَّمِيمَةِ وَأَمَّا الْآخَرُ فَكَانَ لَا يَسْتَتِرُ مِنْ بَوْلِهِ قَالَ فَدَعَا بِعَسِيبٍ رَطْبٍ فَشَقَّهُ بِاثْنَيْنِ ثُمَّ غَرَسَ عَلَى هَذَا وَاحِدًا وَعَلَى هَذَا وَاحِدًا ثُمَّ قَالَ لَعَلَّهُ أَنْ يُخَفَّفُ عَنْهُمَا مَا لَمْ يَيْبَسَا.
