Do we pray witr after Tahajjud or after isha?

So the sunnah is to make the witr the last prayer. The Prophet ﷺ said: اِجَا لُوَاخَرَ صَلَاتِكُمْ بِلَيْلِ وِتَرًا (Make the witr your last prayer of the night). So after you pray tahajjud or taraweeh, that's when you should do your witr prayer. Now let's say for example you go to the mosque and the imam prays the witr prayer and you want to pray later on. You can pray the witr with the imam and you can also pray anything later on if you like. The key thing is that you do not repeat the witr again later on because the Prophet ﷺ said: لَا وِتَرًا فِي لَيْلَ (There's only one witr in the entire night). So the sunnah is to pray the witr at the end. But if you happen to pray it earlier, let's say with the imam at the mosque and you want to pray later on, no problem with that. Just remember, do not do another witr later on.
