Shaking hands etc. after nikaah
Praise be to Allaah.
The answer is, yes, all of this is permitted, even if it happens before the wedding party, so long as the contract has been drawn up according to Sharee’ah, with a guardian and two witnesses, and the proposal has been given and accepted, and both parties consent to the marriage. And Allaah knows best.
Sheikh Muhammed Salih Al-Munajjid
