Surah Al-Baqarah, ayah 221

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 ٢٢١

And do not marry polytheistic women until they believe.⁸¹ And a believing slave woman is better than a polytheist, even though she might please you. And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allāh invites to Paradise and to forgiveness, by His permission. And He makes clear His verses [i.e., ordinances] to the people that perhaps they may remember.
