Good Deed #487 – Salaah and supplication before consummation of marriage
When you enter upon your wife (for the first time), you have first to perform two rak’ats and then hold your wife’s head and say, “O Allah! Bless my wife for me, bless me for my wife, give her bounty out of me, and give me bounty out of her!” Then you can do what you want.”
[Reported by Abu Dawud]
