“Abu Ja‘far (a.s.), once asked me, ‘When one of you marries, does he know what to do?’ I replied, ‘I do not know.’ He (the Imam) said, ‘When he decides for it (marriage) he must perform two Rak’at Salat (prayer) then say, “O Lord, I want to marry so choose for me of women who is most chaste in matters of her private organs, most protective for me of herself and my assets, of most affluence in sustenance and of greatest blessing. Choose for me a fine child to be a virtuous successor in my lifetime and after my death.’” He (the Imam) said, ‘When you meet her place your hand over her forehead and say, “O Lord, according to Your book I have married her, in Your trust I have taken her (in marriage) and with Your words I have made her (private organs) lawful. If You have destined for me from her womb anything (child), then make the child a Muslim, upright and You must not make for Satan any share or portion in it (child).’ I (the narrator) then asked, ‘How can it be a share of Satan?’ He (the Imam) said, ‘Mention of the name of Allah keeps Satan away. If one goes to bed without mentioning the name of Allah, he sticks his penis, the act is from both of them but the seed is one.’”
