In the Name of Allah, the All-Merciful, the Mercy-Giving

 

All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.

 

You need not have any inhibitions about intimacy with your wife after Nikah. Nikah renders each one of you lawful for the other. If she has agreed to accept a deferred mahr payment

However, if you postpone sexual intercourse until you bring her home or until you pay the mahr promised that is up to both of you.

 

There is no hard and fast rule in such matters in Islam.

 

Almighty Allah knows best.
