Using someone else’s Internet connection or network?
In the name of Allah, the most Beneficent, the most Merciful.
The general ruling is that one cannot use another’s property without their permission. In most countries, it is against the law to use other peoples internet connection or network.
Therefore, because it is another’s property it is not permissible to take their property without explicit permission.
Furthermore, the Prophet of Allah Sallallahu Alahi Wasalam has said:
“A Muslim may not take another’s property without their permission.” (Sunan Baihaqi)
Only Allah Knows Best.
