Q 2: What
is the ruling on the salary that a bank officer receives?
If the concerned bank is not usurious, the salary the officers receive is Halal (lawful) for it is received against permissible work. On the contrary, if a bank is usurious, any salary received by the officers is Haram (prohibited) as it involves helping in sin and transgression while Allah (Exalted be He) says:
Help you one another in Al-Birr and At-Taqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression.
The Prophet (peace be upon him) cursed the one who accepts Riba (Usury), the one who gives it, those who witness it, and the one who writes it. He (peace be upon him) said: They are equal (in sin).

May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
