The Prophet (sal Allaahu alayhi wa sallam ) passed by two graves. He said : Both (the dead) are being punished, but they are not being punished for a major (sin). One did not safeguard himself from urine. The other carried tales. He then called for a fresh twig and split it into two parts and planted one part on each grave and said: Perhaps their punishment may be mitigated as long as the twigs remain fresh. Another version of Hannad has: "One of them did not cover himself while urinating." This version does not have the words: "He did not safeguard himself from urine."  

مَرَّ رَسُولُ اللَّهِ ﷺ عَلَى قَبْرَيْنِ فَقَالَ إِنَّهُمَا يُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا هَذَا فَكَانَ لاَ يَسْتَنْزِهُ مِنَ الْبَوْلِ وَأَمَّا هَذَا فَكَانَ يَمْشِي بِالنَّمِيمَةِ ثُمَّ دَعَا بِعَسِيبٍ رَطْبٍ فَشَقَّهُ بِاثْنَيْنِ ثُمَّ غَرَسَ عَلَى هَذَا وَاحِدًا وَعَلَى هَذَا وَاحِدًا وَقَالَ لَعَلَّهُ يُخَفَّفُ عَنْهُمَا مَا لَمْ يَيْبَسَا قَالَ هَنَّادٌ يَسْتَتِرُ مَكَانَ يَسْتَنْزِهُ  

A tradition from the Prophet (sal Allaahu alayhi wa sallam ) conveying similar meaning. The version of Jarir has the wording : "he did not cover himself while urinating." The version of Abu Mu'awiyah has the wording: "he did not safeguard himself (from urine)."  

عَنِ النَّبِيِّ ﷺ بِمَعْنَاهُ قَالَ كَانَ لاَ يَسْتَتِرُ مِنْ بَوْلِهِ وَقَالَ أَبُو مُعَاوِيَةَ يَسْتَنْزِهُ  

AbdurRahman ibn Hasanah reported: I and Amr ibn al-'As went to the Prophet ﷺ. He came out with a leather shield (in his hand). He covered himself with it and urinated. Then we said: Look at him. He is urinating as a woman does. The Prophet ﷺ, heard this and said: Do you not know what befell a person from amongst Banu Isra'il (the children of Israel)? When urine fell on them, they would cut off the place where the urine fell; but he (that person) forbade them (to do so), and was punished in his grave. Abu Dawud said: One version of Abu Musa has the wording: "he cut off his skin". Another version of Abu Musa goes: "he cut off (part of) his body."  

انْطَلَقْتُ أَنَا وَعَمْرُو بْنُ الْعَاصِ إِلَى النَّبِيِّ ﷺ فَخَرَجَ وَمَعَهُ دَرَقَةٌ ثُمَّ اسْتَتَرَ بِهَا ثُمَّ بَالَ فَقُلْنَا انْظُرُوا إِلَيْهِ يَبُولُ كَمَا تَبُولُ الْمَرْأَةُ فَسَمِعَ ذَلِكَ فَقَالَ أَلَمْ تَعْلَمُوا مَا لَقِيَ صَاحِبُ بَنِي إِسْرَائِيلَ كَانُوا إِذَا أَصَابَهُمُ الْبَوْلُ قَطَعُوا مَا أَصَابَهُ الْبَوْلُ مِنْهُمْ فَنَهَاهُمْ فَعُذِّبَ فِي قَبْرِهِ
