Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "When a woman is brought to her husband, the man should stand and the woman should stand behind him, and the two of them should pray two rak'ahs, and then they should supplicate: 'Allahumma barik li fi ahli wa barik li-ahli fiyya, Allahumma-rzuqhum minni wa-rzuqni minhum, Allahumma-jma' baynana ma jama'ta fi khayr, wa farriq baynana idha farraqta ila khayr' (O Allah, bless me in my family and bless my family in me. O Allah, provide for them through me and provide for me through them. O Allah, keep every kind of goodness between us, and when You separate us from one another, separate us towards goodness)."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Isma'il bin Ibrahim bin al-Mughirah al-Marwazi, whom I have not found anyone mentioning, and a narrator, Ata' bin al-Sa'ib, who suffered from confusion (ikhtilat); the rest of its narrators are thiqat (trustworthy).
