Sheikh I said a kufr word in the Quran and hated saying it and repented from it when I come across that kufr verse in the Quran it reminded me of my sin should I skip that verse or act like it never happened and read the verse pliz advice

All perfect praise be to Allah, The Lord of the Worlds. I testify that none is worthy of worship except Allah and that Muhammad is His slave and messenger.

As long as you have repented to Allah, then repentance erases all sins committed before it. The one who repents from sin is like one who has not sinned.

So, whenever you come across that verse, you should recite it normally without worrying about what you did in the past.

Allah Knows best.
