Is the suitor entitled to retrieve the dowry he paid to the fiancée's father before the marriage contract, given that the contract was not concluded, and he only saw the fiancée briefly and had phone calls with her father's approval, and that the father stipulated delaying the contract until preparations for the marriage were complete, which caused displeasure to the suitor?

If the marriage contract has not yet been concluded, and the suitor decides to withdraw from the engagement before the contract, he has the right to reclaim all the dowry he paid, whether the withdrawal was from his side or the fiancée's side. This is by agreement among the scholars, as the dowry is linked to the marriage contract, not merely to the engagement. This also applies to gifts given with the intention of being part of the dowry.
