Fussilat 41:42

لَّا يَأْتِيهِ ٱلْبَـٰطِلُ مِنۢ بَيْنِ يَدَيْهِ وَلَا مِنْ خَلْفِهِۦ ۖ تَنزِيلٌ مِّنْ حَكِيمٍ حَمِيدٍ

Lā yatīhi l-bāṭilu min bayni yadayhi walā min khalfihi tanzīlun min ḥakīmin ḥamīdin

Falsehood cannot approach it from before it or from behind it; [it is] a revelation from a [Lord who is] Wise and Praiseworthy.
