Islām is Inherently Prejudicial (And There's Nothing Wrong with That)!!!
In general, Muslims and non-Muslims are treated differently in this life and in the Hereafter!
Allāh stated:أَمْ حَسِبَ الَّذِينَ اجْتَرَحُوا السَّيِّئَاتِ أَن نَّجْعَلَهُمْ كَالَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ سَوَاءً مَّحْيَاهُمْ وَمَمَاتُهُمْ ۚ سَاءَ مَا يَحْكُمُونَ
"Or
do those who commit evils think We will make them like those who have
believed and done righteous deeds - (make them) equal in their life and
their death? Evil is that which they judge." [Sūrat al-Jāthiyah, 21]
It is unacceptable for non-Muslim women, other than those from the People of the Book, to marry Muslim men!
Allāh stated:وَلَا تَنكِحُوا الْمُشْرِكَاتِ حَتَّىٰ يُؤْمِنَّ ۚ وَلَأَمَةٌ مُّؤْمِنَةٌ خَيْرٌ مِّن مُّشْرِكَةٍ وَلَوْ أَعْجَبَتْكُمْ ۗ وَلَا تُنكِحُوا الْمُشْرِكِينَ حَتَّىٰ يُؤْمِنُوا ۚ وَلَعَبْدٌ مُّؤْمِنٌ خَيْرٌ مِّن مُّشْرِكٍ وَلَوْ أَعْجَبَكُمْ
"And
do not marry polytheistic women until they believe. 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." [Sūrat al-Baqarah, 221]
And He stated:
الْيَوْمَ
أُحِلَّ لَكُمُ الطَّيِّبَاتُ ۖ وَطَعَامُ الَّذِينَ أُوتُوا الْكِتَابَ
حِلٌّ لَّكُمْ وَطَعَامُكُمْ حِلٌّ لَّهُمْ ۖ وَالْمُحْصَنَاتُ مِنَ
الْمُؤْمِنَاتِ وَالْمُحْصَنَاتُ مِنَ الَّذِينَ أُوتُوا الْكِتَابَ مِن
قَبْلِكُمْ إِذَا آتَيْتُمُوهُنَّ أُجُورَهُنَّ مُحْصِنِينَ غَيْرَ
مُسَافِحِينَ وَلَا مُتَّخِذِي أَخْدَانٍ
"This
day (all) good foods have been made lawful, and the food of those who
were given the Scripture is lawful for you and your food is lawful for
them. And (lawful in marriage are) chaste women from among the believers
and chaste women from among those who were given the Scripture before
you, when you have given them their due compensation, desiring chastity,
not unlawful sexual intercourse or taking (secret) lovers." [Sūrat al-Mā’idah, 5]
