Working in an institute teaching interest-based financial courses

Allaah says (interpretation of the meaning):

“Help you one another in Al-Birr and At-Taqwa (virtue,
righteousness and piety); but do not help one another in sin and transgression”
[al-Maa’idah 5:2]. Your working in this institute is clearly helping them to
continue engaging in riba, which is something that is forbidden not only in Islam but in
all religious laws revealed to other Prophets. The Prophet
(peace and blessings of Allaah
be upon him) said: “Allaah has cursed the one who consumes riba, the one who gives
riba, the one who writes it down and the one who witnesses it.” He said: “They
are all the same.”

(Narrated by Muslim).

So you have to look for a new job. The Prophet
(peace
and blessings of Allaah be upon him) said: “You never give up anything out of fear of
Allaah, but Allaah will give you something better than that.”

(Narrated by
Ahmad).

And Allaah says (interpretation of the meaning):

“And whosoever fears Allaah and keeps his duty to Him, He will
make a way for him to get out (from every difficulty). And He will provide him from
(sources) he never could imagine. And whosoever puts his trust in Allaah, then He will
suffice him.” [al-Talaaq 65:2-3]

And Allaah knows best.
