A mischief-maker will not enter paradise.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَدْخُلُ الْجَنَّةَ قَتَّاتٌ  

I heard Messenger of Allah ﷺ saying: The tale-bearer shall not enter Paradise.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ يَدْخُلُ الْجَنَّةَ نَمَّامٌ  

"The Messenger of Allah passed by two new graves, and he said: 'They are being punished, but they are not being punished for anything major. One of them was heedless about preventing urine from getting on his clothes, and the other used to walk about spreading malicious gossip.'"  

مَرَّ رَسُولُ اللَّهِ ﷺ بِقَبْرَيْنِ جَدِيدَيْنِ فَقَالَ إِنَّهُمَا لَيُعَذَّبَانِ وَمَا يُعَذَّبَانِ فِي كَبِيرٍ أَمَّا أَحَدُهُمَا فَكَانَ لاَ يَسْتَنْزِهُ مِنْ بَوْلِهِ وَأَمَّا الآخَرُ فَكَانَ يَمْشِي بِالنَّمِيمَةِ  

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
