(18) بَابُ قَوْلِ اللَّهِ تَعَالَى: {وَلاَ تَنْكِحُوا الْمُشْرِكَاتِ حَتَّى يُؤْمِنَّ وَلأَمَةٌ مُؤْمِنَةٌ خَيْرٌ مِنْ مُشْرِكَةٍ وَلَوْ أَعْجَبَتْكُمْ}
Narrated Nafi`:
Whenever Ibn `Umar was asked about marrying a Christian lady or a Jewess, he would say: "Allah has made it unlawful for the believers to marry ladies who ascribe partners in worship to Allah, and I do not know of a greater thing, as regards to ascribing partners in worship, etc. to Allah, than that a lady should say that Jesus is her Lord although he is just one of Allah's slaves."
