Is Doing Rafa Yadein Compulsory?
The prophet before fatah Mecca Used to do the rafayedain because the kuffar used to put idols under their armpits. But when the prophet sallahu alaihay wassalm migrated to madina he stopped it and made it mansookh. There is a sahih hadeeth in Bukhari shareef where the prophet comes out and sees the sahabs praying and doing the rafayadain. He tells them not to do it.

There’s nothing in the Quran for or against it.
