Read and reflect on verse 321 from Surah Aal-i-Imraan: LET NOT the believers take those who deny the truth for their allies in preference to the believers - since he who does this cuts himself off from God...
لَا يَتَّخِذِ الْمُؤْمِنُونَ الْكَافِرِينَ أَوْلِيَاءَ مِنْ دُونِ الْمُؤْمِنِينَ ۖ وَمَنْ يَفْعَلْ ذَٰلِكَ فَلَيْسَ مِنَ اللَّهِ فِي شَيْءٍ إِلَّا أَنْ تَتَّقُوا مِنْهُمْ تُقَاةً ۗ وَيُحَذِّرُكُمُ اللَّهُ نَفْسَهُ ۗ وَإِلَى اللَّهِ الْمَصِيرُ
LET NOT the believers take those who deny the truth for their allies in preference to the believers - since he who does this cuts himself off from God in everything - unless it be to protect yourselves against them in this way. But God warns you to beware of Him: for with God is all journeys' end.
