Salaam Alaykum Sheikh. Is it permisssible to work in a factory where football shirts are made and shipped but some of them have haraam companies sponsoring them like betting companies and interest based banks. The job itself would be QA, basically checking if the item is clean and undamaged.

Ustadh AbdulAziz al-Haqqan

Allowed in sha'a Allah as you are only checking the damaged and undamaged goods.
