Mishkat al-Masabih 3321
He reported the Prophet as saying, “There are four types of women with whom there can be no cursing:
* a Christian woman married to a Muslim, a Jewess married to a Muslim, a freewoman married to a slave, and a slave woman married to a freeman.” 
*That is the mutual invoking of curses with which this chapter deals.

Ibn Majah transmitted it.
وَعَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: 
" أَرْبَعٌ مِنَ النِّسَاءِ لَا مُلَاعَنَةَ بَيْنَهُنَّ: النَّصْرَانِيَّةُ تَحْتَ الْمُسْلِمِ وَالْيَهُودِيَّةُ تَحْتَ الْمُسْلِمِ وَالْحُرَّةُ تَحْتَ الْمَمْلُوكِ وَالْمَمْلُوكَةُ تَحْتَ الْحُرِّ ". رَوَاهُ ابْنُ مَاجَه
