All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The Muslim’s aim should always be the Hereafter. He should prefer the coming life over this worldly life. This life is very short and soon will end. But the real life is the hereafter, which is endless and everlasting. So you know that usury is prohibited in Islam; all companies, banks etc, that are dealing with usury are forbidden in Islam.
Allah Says (what means): {And cooperate in righteousness and piety, but do not cooperate in sin and aggression.} [Quran 5:2]
Your work with them is real cooperation.
Jaabir narrated that the Prophet said “Allah has cursed the one who consumes Riba (i.e. usury or interest), the one who gives it to others, the one who records it and the one who witnesses it (its transaction).” He added: “All of them are equal in sin.” [Muslim]
May Allah bless you and provide you with lawful jobs and earnings.
Allah knows best.
