“Abu al-Hassan, al-Rida’ (a.s.), once said to me, ‘O abu Muhammad, what do you say about a man who marries a Jewish or a Christian woman, as a second wife, the first being a Muslim woman?’ I replied, ‘I pray to Allah to keep my soul in service for your cause, my words have no meaning in your presence.’ He (the Imam) said, ‘You must say it; with it my words will come to light.’ I said, ‘It is not lawful to marry a Christian woman as a second wife, the first being a Muslim woman or non-Muslim woman.’ He (the Imam) asked, ‘Why is it so?’ I replied, ‘It is because of the words of Allah, most Majestic, most Glorious, “You must not marry the pagan women until they become believers.’” (2:221) He (the Imam) then asked, ‘What do you say about, “Marry of the chaste woman of the followers of the book (bible) which was before you” (5:5)?’ I replied, ‘Verse 221 of Chapter 2 has cancelled verse 5:5.’ He (the Imam) smiled and remained quiet.’”
