What one does on going in to his wife

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: Sayyiduna Salman al-Farisi (may Allah be pleased with him) returned after (a long) absence, and he met Sayyiduna Umar (may Allah be pleased with him), who said: "May Allah be pleased with you." The narrator says: He had married in Kindah. When the night came on which his bride was to be brought to him, the house was full and there were women in it. He asked: "Has the Ka'bah moved to Kindah, or is this woman of mine red-complexioned? My intimate friend, Sayyiduna Abu al-Qasim (peace and blessings be upon him), commanded me that we should keep no more belongings than a traveller's provisions, and keep no more women than those we marry." So the women left the house, and he went in to his wife and said: "O lady! Will you obey me or disobey me?" She replied: "I will obey you in whatever you wish." Sayyiduna Salman al-Farisi (may Allah be pleased with him) said: "My intimate friend commanded me that when one of us goes in to his wife, he should stand and pray, and instruct her to stand behind him and pray, and he should supplicate and she should say Amin." The narrator says: So Sayyiduna Salman al-Farisi (may Allah be pleased with him) did so, and his wife did so too. The next day, when he was sitting in a gathering of the people of Kindah, a man asked him: "O Abu Abdullah! How are you? How did you find your wife?" He remained silent. The man asked again, so Sayyiduna Salman (may Allah be pleased with him) said to him: "What is the matter with one of you, that he asks about something that walls and doors have concealed? It is enough for any of you that if he asks about something, then if he is given an answer, that is fine, and if he is not given an answer (that is also fine)."
Imam al-Tabarani recorded it in this way.

Imam al-Bazzar recorded it, and he says: Sayyiduna Salman al-Farisi (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "When one of you marries, then on the wedding night he should pray two rak'ahs and instruct his wife to pray behind him as well; in this way Allah Almighty will place goodness in his home." The chains of both these narrations contain a narrator, al-Hajjaj bin Farrukh, who is da'if (weak).

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).

Abu Wa'il narrates: A man from Bajilah came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) and said: "I have married a virgin girl, and I fear that she will come to detest me." Sayyiduna Abdullah (may Allah be pleased with him) said: "Beware! Affection is from Allah Almighty, and aversion is from Satan, so that he may make hateful to a person what Allah Almighty has made lawful. When she is brought to you, instruct her to pray two rak'ahs behind you." Al-A'mash narrates: I mentioned this to Ibrahim, and he said: Sayyiduna Abdullah (may Allah be pleased with him) said: "And supplicate: 'Allahumma barik li fi ahli wa barik lahum fiyya, Allahumma-rzuqhum minni wa-rzuqni minhum, Allahumma-jma' baynana ma jama'ta ila khayr, wa farriq baynana idha farraqta ila al-khayr' (O Allah, bless me in my family and bless them in me. O Allah, provide for them through me and provide for me through them. O Allah, as long as You keep us together, keep us together towards goodness, and when You separate us, separate us towards goodness)."
Imam al-Tabarani recorded it, and its narrators are the narrators of the Sahih.
