Al-Hasan was asked about the neighbour and said, "The term 'neighbour' includes the forty houses in front a person, the forty houses behind him, the forty houses on his right and the forty houses on his left."  

عَنِ الْجَارِ فَقَالَ أَرْبَعِينَ دَارًا أَمَامَهُ وَأَرْبَعِينَ خَلْفَهُ وَأَرْبَعِينَ عَنْ يَمِينِهِ وَأَرْبَعِينَ عَنْ يَسَارِهِ  

Abu Hurayra said, "Do not begin with your more distant neighbours before the closer ones. Rather begin with your nearest neighbours before the most distant ones."  

سَمِعْتُ أَبَا هُرَيْرَةَ قَالَ وَلاَ يَبْدَأُ بِجَارِهِ الأَقْصَى قَبْلَ الأَدْنَى وَلَكِنْ يَبْدَأُ بِالأَدْنَى قَبْلَ الأَقْصَى
