I just want to have a better understanding of what Jannah will have in the afterlife. Are all sins on Earth will be forbidden in Jannah? Or are some actions that are forbidden on Earth will be allowed in Jannah? I researched about this topic and I found these Ayat in the Qur'an:

"They will not hear therein ill speech or commission of sin"


"They will exchange with one another a cup [of wine] wherein [results] no ill speech or commission of sin."


It seems like the inhabitants of Jannah will never be able to sin. Though will there be actions that were sins in this life to be allowed in the afterlife?

The life in Jannah is different than the life on earth, as I mentioned earlier. There every thing is permissible. However, the dirty things on earth does not exist there, so the wine in Jannah is not the same wine on earth, as it is mentioned in Quran
لَا فِيهَا غَوْلٌ وَلَا هُمْ عَنْهَا يُنْزَفُونَ
Sura 37, verse 47
