If the Sale was Valid

My father put up a plot of land for sale. A buyer came forward and after we agreed on the sale we recited Surat Al-Fatiha together. The next day, this same man came with another buyer to show him the land and on the third day he came with yet another one. 

We realized that he was a broker and my father and brother told him that the agreement had been revoked and the sale is not effective unless he makes a down payment; he left without making one and did not return.
