Hadith on Neighbors: How many bad neighbors on Judgment Day?

Ibn Umar reported: The Messenger of Allah, peace and blessings be upon him, said, “How many neighbors will be brought with their neighbors on the Day of Resurrection? One will say: O Lord, this man closed his door to me and he refused to show courtesy.”

عَنِ ابْنِ عُمَرَ قَالَ‏ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ‏ كَمْ مِنْ جَارٍ مُتَعَلِّقٌ بِجَارِهِ يَوْمَ الْقِيَامَةِ يَقُولُ‏ يَا رَبِّ هَذَا أَغْلَقَ بَابَهُ دُونِي فَمَنَعَ مَعْرُوفَهُ‏
