Answer
(Fatwa: 967/965/N=1433)
If the owner of your company is non-Muslim then the salary which you derive on your service is lawful and halal absolutely for you as the interest which a non-Muslim gets is halal for him and he becomes its owner (Baqiyat Fatawa Rashidiya p. 227 and Azizul Fatawa p. 598). And there will not come any malice due to earning interest from other’s money as that money has come under the risk of non-Muslim (owner of the company). But if the owner of the company is Muslim then it is wajib for him to give this interest money in charity. And in this case if the company gives you salary without the explanation of interest and does not reveal to you that the money which is given to you contains so and so money of interest – it is obvious that the company does not tell rather it is not necessary that it pays you the salary with interest money – then too your salary shall be lawful and acceptable. Do not have any doubt regarding your salary.
