According to the Islamic perspective on Waqf , in 1417 AH Sheikh Saleh ibn Abdulaziz Alrajhi allocated some of his property for endowment. The proceeds of the donated property should be used in the identified twelve channels stated in the Endowment instrument. Then a board of managing the endowments of Saleh Abdulaziz Alrajhi was established in order to achieve the following objectives:
1- To manage and maintain the real estates and farms endowed by Sheikh Saleh Abdulaziz Alrajhi
2- To invest the part assigned for investment to grow the endowment.
3-To maintain the existing endowments
4- To spend the revenues of those endowed assets in the channels identified by the donor.
