وَلَا تَنكِحُواْ ٱلۡمُشۡرِكَٰتِ حَتَّىٰ يُؤۡمِنَّۚ وَلَأَمَةٞ مُّؤۡمِنَةٌ خَيۡرٞ مِّن مُّشۡرِكَةٖ وَلَوۡ أَعۡجَبَتۡكُمۡۗ وَلَا تُنكِحُواْ ٱلۡمُشۡرِكِينَ حَتَّىٰ يُؤۡمِنُواْۚ وَلَعَبۡدٞ مُّؤۡمِنٌ خَيۡرٞ مِّن مُّشۡرِكٖ وَلَوۡ أَعۡجَبَكُمۡۗ أُوْلَٰٓئِكَ يَدۡعُونَ إِلَى ٱلنَّارِۖ وَٱللَّهُ يَدۡعُوٓاْ إِلَى ٱلۡجَنَّةِ وَٱلۡمَغۡفِرَةِ بِإِذۡنِهِۦۖ وَيُبَيِّنُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمۡ يَتَذَكَّرُونَ
Do not marry polytheist women until they believe; for a believing slave woman is better than a free polytheist, even though she may attract you. And do not give your women in marriage to polytheist men until they believe, for a believing slave is better than a free polytheist, even though he may attract you. They invite to the Fire while Allah invites to Paradise and to forgiveness by His grace, and He makes His verses clear to people so that they may take heed.
- i.e., worship and obey Allah alone.
