Answered by Shaykh Faraz Rabbani
If a software package which has not been purchased, but copied, is used to create a program, would the money made from that program be Haram?
Walaikum assalam wa rahmatullah,
While one is expected to uphold the limits of copyright law, money earned using pirated software would not be unlawful or sinfully earned.’
However, scholars if spiritual insight and piety (taqwa) mention that there is more baraka (blessings) in one’s earnings when one uses legitimately-acquired software whenever reasonably possible: a Muslim lives within the law.
