I am confused if istinja is part of wudu because one has to perform wudu before performing salah but does this mean they have to perform istinja too?
When I search online on how to do wudu, look in some books or even Islamic shows on the TV that show how to do wudu, they do not include istinja as a step. Also at college when people pray they do not perform istinja, but does that mean their salah is invalid as they are not in a complete state of purity?
My questions:
1) Is istinja part of wudu
2) Does one have to perform istinja before salah?
Please include where you got the information from e.g. quote hadith.
