What is the evidence upon which scholars based their justification that permits a man and a woman to meet after the marriage contract (nikah) but before the consummation of the marriage, given that the Prophet, may God’s prayers and peace be upon him, did not meet Aisha, may God be pleased with her, alone during the period between the marriage contract and the consummation of the marriage?

A man is a stranger to a woman, and nothing about her becomes permissible for him until he marries her. Once the marriage contract is concluded, she becomes his wife, and everything about her becomes permissible for him, including looking at her, being alone with her, and shaking her hand, because the marital relationship is established by the contract. People commonly agree that the announcement of the marriage contract should be distinct from the announcement of consummation, due to the husband's circumstances. Therefore, the husband does not consummate the marriage with his wife until after the announcement of consummation, to avoid embarrassment and suspicion. As for the claim that the Prophet did not meet Aisha privately after the contract until consummation, this is an unsubstantiated claim.
