Answer
(Fatwa: 120/89=H/1429)
Hadhrat Jabir (رضی اللہ عنہ) narrates that the Prophet (صلی اللہ علیہ وسلم) cursed those who consume interest, give interest, write account of interest and bear witness to it. He said that all are equal in sin. (Sahih Muslim, Mishkwat 244) There are more traditions and verses which proclaim numerous punishments for interest and its dealings. In view of the same, you should yourself see, if your work in any way is not related to interest, then obviously your employment is within lawful limits.
