1) I have slept in morning and when I woke up I realized that my pants is wet 10 minutes after I woke up. The first thing that comes to my mind that I suspect that is wet dream because but in fact there is no semen in my private parts nor do I know and feel that I have ejaculated and also I do not have lustful dreams. Is it considered najis?

2) Some of my things have been najis and have mixed with non najis things, and because of that I don’t know which is najis or not. What is your take on that?

1) If you’re not sure and there is no sign of wet dream then there is nothing on you. Because sometimes it happens while there is no trace of wet dreams. But if you have doubt and not sure then do Ghusl

2) Clean your all things which has been mixed with other najis things.
