Respected Mufti Saheb

1 – Is it permissible to take a Chinese calculator (Kenko) remove the label and replace it with a Casio label and sell it as a Casio

2- If not permissible what is the condition of the earnings derived from this sale

3 – What is the status of a Aalim/Mufti who says it is permissable

Jazakumullah

Wasalaam
