عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو رَضِيَ اللَّهُ عَنْهُ، أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ”يَطَّلِعُ اللَّهُ عَزَّ وَجَلَّ إِلَى خَلْقِهِ لَيْلَةَ النِّصْفِ مِنْ شَعْبَانَ، فَيَغْفِرُ لِعِبَادِهِ إِلَّا لِاثْنَيْنِ: مُشَاحِنٍ وَقَاتِلِ نَفْسٍ“
It is narrated from Sayyiduna Abdullah bin Amr bin Aas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty looks upon His creation on the night of mid-Sha’ban and forgives all His servants, except for two types of people: one who harbors enmity against someone, and one who is a murderer.
