Praise
be to Allah
If your using the internet will not lead to increased charges for this
person because of your downloading or uploading anything via the internet,
and will not cause any slowdown or other problems because of increased
traffic or sharing the connections, then the general meaning of tolerance
between neighbours and the hadeeth of Abu Hurayrah in which the Prophet
(peace and blessings of Allaah be upon him) said “No neighbour should
prevent his neighbour from fixing a piece of wood to his wall” (narrated by
al-Bukhaari (2463) and Muslim (1609)) indicates that it is permissible for
you to use the internet in this case, but in order to be on the safe side it
is better to ask your neighbour’s permission if you know him.
But there are some reservations concerning this issue, such as if the area
is covered by more than one connection belonging to more than one neighbour,
so your computer may connect to one at one time and another at another time.
There is also the issue of the losses of customers and profits incurred by
the telecommunications company because of this taking advantage of
neighbours’ coverage. Hence to be on the safe side it is better to sign up
for your own account so that you may avoid these dubious matters..
And Allaah knows best.
