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."
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."
'A'isha said, "I said, 'Messenger of Allah, I have two neighbours. To
whom should I give my gifts?' He replied, 'To the one whose door is nearer
to you.'"
