We know that when someone is sitting after prayer, then they are rewarded as if they are still praying. And if someone is waiting til the next prayer then this is like Jihad. And you answered me that the reward is there if I pray at home. What nullifies the ongoing reward? Does breakign wudu nullify

Ustadh AbdulAziz al-Haqqan

Yes, breaking your wudu ends it, and I believe I said it is from jihad (striving) to do so.
