I dunt know why you ppl get your knickers in a twisst ...sorry to say it so bluntly
For a Gurl.. she duntsay anything except Yes or a No .. or just makes a somesorta sign of approval or stays quiet ..meaning she accepts .. THATS IT !!!!!
For a Guy.. If the Guy dunt know anything what the Molwi tells him to read .. which is usually Imaan e Mufassil and the FiRST 3 KAlmahs.. and if he dunt know it then the molwi reads it and the GUY follows ..then his permission is asked ...and he has to say yes 3 times or a no once... once hes done .. the final Dua is made by the Molwi ..
Thas it!!!!
Quite frankly, I don't know if you are a girl or a guy, neither do I care, but that's the stupid-est thing I have ever heard in my life.
If a girl makes 'some sort of a sign or stays quiet' does not mean she accepts. She also has to say kabool hai 3 times, atleast loudly so the witnesses and the molvi hear her... I don't know what kind of a religion you practice, cuz a girl remaining quiet during her nikkah isn't referred to as a 'yes' in Islam. And you don't need to be an expert on Islam to know that... sorry to say it so bluntly.
