Question:
What is the evidence that explicitly proposing marriage to a woman in her waiting period is forbidden?

Answer:
But there is no with him, so it is permissible to hint without being explicit. Yes, the meaning of "secretly" is marriage; do not make secret appointments with them for marriage, meaning do not be explicit and say, "I want to marry you" or "I want to give you in marriage." This is not permissible because she might rush and say, "My waiting period has ended," if she becomes desirous of the husband and says, "My waiting period is over," when it has not actually ended. Therefore, this is prohibited. Yes.
