1. It is not permissible to render service or to assist someone in any matter that is impermissible in shariah. In doing so, one will be aiding the person in works of sin and this has been condemned in the Qur’aan Majeed. Allah Ta’ala mentions in the Qur’aan Majeed:
وَتَعَاوَنُوا عَلَى البِرِّ وَالتَّقْوٰى وَلَا تَعَاوَنُوا عَلَى الْإِثمِ وَالعُدْوَان
“Assist one another in (works of) righteousness and piety, and do not assist one another in sin and transgression”
