۞ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَتَّخِذُوا۟ ٱلْيَهُودَ وَٱلنَّصَٰرَىٰٓ أَوْلِيَآءَ ۘ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍۢ ۚ وَمَن يَتَوَلَّهُم مِّنكُمْ فَإِنَّهُۥ مِنْهُمْ ۗ إِنَّ ٱللَّهَ لَا يَهْدِى ٱلْقَوْمَ ٱلظَّٰلِمِينَ
O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you - then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people.
In Arabia, in the early days of Islam, the Jews and Christians held a monopoly of the major economic resources of the country, and made efforts day and night to uproot the Muslims, who were as yet a newly emerging force. The people, deeply impressed by the centuries of history which reinforced the greatness of the Jews and the Christians, saw them as having such power that they could never be overthrown. The weaker members of the Muslim community did not, therefore, want to take part in Islamic efforts in such a way as to displease them, for if this struggle ended in defeat for the Muslims, they would have to face the vengeful retaliation of these powerful enemies. In order to protect themselves from future danger, they lived in a state of dual loyalty, which itself was not without its hazards. They lost sight of the fact that worshipping the Truth solely in unimportant matters would not stand them in good stead if, once faced with danger, they lent their support to upholders of falsehood: their fate would inevitably be no different from the fate of those they had co-operated with whenever they felt imperiled.
