"Indeed, they are enemies to me, except for the Lord of the worlds," meaning: except for whoever worshiped the Lord of the worlds among your forefathers of old; for he is not an enemy to me. This is the interpretation of al-Hasan.
﴿فَإِنَّهُمْ عَدُوٌّ لِي إِلا رَبَّ الْعَالمين﴾ أَيْ: إِلَّا مَنْ عَبَدَ رَبَّ الْعَالَمِينَ مِنْ آبَائِكُمُ الْأَوَّلِينَ؛ فَإِنَّهُ لَيْسَ لِي بِعَدُوٍ؛ هَذَا تَفْسِيرُ الْحسن
