The Share of Each Partner in the Sale of a Property

Q: We are a few partners who bought a property. One partner gave R1 million and the others gave R5 million. Before selling the property, we told the partner who gave R1 million that we will give him R20 000 of the profit. Hence, we fixed the amount of profit to be given to him before selling the property. After selling the property, we gave him R20 000. Is this permissible?
