quran:16:37 –

˹Even˺ if you should strive for their guidance, ˹O Muhammad˺, indeed, Allah does not guide those He sends astray, and they will have no helpers.  

If you, O Muhammad (s), are eager for them to be guided, when God has already made them go astray, you will not be able to achieve this: For God does not guide (read passive lā yuhdā ˹?˺, or active lā yahdī) he whom He has ˹already˺ sent astray, he whom He desires to send astray, and they will have no helpers, ˹no˺ protectors from God’s chastisement.
القرآن:١٦:٣٧ –

إِنْ تَحْرِصْ عَلَىٰ هُدَاهُمْ فَإِنَّ اللَّهَ لَا يَهْدِي مَنْ يُضِلُّ ۖ وَمَا لَهُمْ مِنْ نَاصِرِينَ  

{إن تحرص} يا محمد {على هداهم} وقد أضلهم الله لا تقدر على ذلك {فإن الله لا يُهدِي} بالبناء للمفعول وللفاعل {من يضل} من يريد إضلاله {وما لهم من ناصرين} مانعين من عذاب الله.
