"And if the Truth had followed their desires," meaning: the desires of the polytheists, "the heavens and the earth would have been corrupted." Al-Hasan's interpretation says: If the Truth were according to their desires, their desires would have resulted in the destruction of the heavens and the earth. "Rather, We have brought them their Reminder," meaning: their honor; it is an honor for whoever believes in it, "but they are from their Reminder [from their honor] turning away."
﴿وَلَو اتبع الْحق أهواءهم﴾ يَعْنِي: أهواء الْمُشْركين ﴿لفسدت السَّمَاوَات وَالْأَرْض﴾ تَفْسِير الْحسن يَقُول: لَو كَانَ الْحَقُّ فِي أَهْوَائِهِمْ لَوَقَعَتْ أَهْوَاؤُهُمْ عَلَى إِهْلَاكِ السَّمَوَاتِ وَالْأَرْضِ ﴿بَلْ أتيناهم بذكرهم﴾ أَيْ: بِشَرَفِهِمْ؛ هُوَ شَرَفٌ لِمَنْ آمَنَ بِهِ ﴿فَهُمْ عَنْ ذِكْرِهِمْ﴾ [عَنْ شَرَفِهِمْ] ﴿مُعْرِضُونَ﴾.
