Praise be to Allaah.
If the marriage contract has been done and all the shar’i conditions have been met, then they are husband and wife according to the sharee’ah of the Lord of the Worlds. It is permissible for them to sit together, talk and be alone together in complete freedom.
The Standing Committee for Issuing Fatwas was asked: what is permissible between a husband and wife after the contract has been done and before consummation of the marriage. They replied:
Whatever is permissible between a husband and a wife with whom the marriage has been consummated is permissible – such as looking, kissing, being alone together, travelling with her, intercourse, etc.
