Is it permissible to buy an existing company mainly to use its genuine past financial history to qualify for Saudi investment/residency, if the authority knows ownership changed and the old assets are gone, and I will genuinely own it and operate a real business afterward?

Ustadh AbdulAziz al-Haqqan

If buying the company and using its history is within what the regulations allow, with no lying or hiding anything from the authority, there is no harm in it. otherwise it is not.
