insurance donations

Dear respected Mufti Saheb
Assalamualaikum
Can Mufti Saheb please give a fatwa on the following:
Can money donated to the masjid from a muslim company that deals in insurance be accepted by the masjid committee?
Also if the money was received from rentals of property owned by the above company will it be permissable to accept it for the masjid?… We are uncertain if the properties were acquired with insurance monies or not.
Jazakallah
Wasalaam
