Re: The whole concept of husband as a mijazi khuda...
There is no "title" such as this, however it finds its roots in the sound hadeeth of the Prophet SAW, when he is reported to have said,
"If I were to order anyone to prostrate to other than Allah, I would have ordered the woman to prostrate to her husband. By Him in whose Hand is the soul of Muhammad, the woman will not fulfill the rights of her Lord until she fulfills the rights of her husband...."
[Sahih, reported by Ibn Maajah and Ahmad from Abdullah ibn Awfaa]
Men usually misuse this saying of the Prophet SAW and make themselves as kings who must be respected and served no matter what they do and how they behave. No doubt women should not be disobedient to their husbands as it is a sin for them to do that as well.
JazakAllah....
I think Mijazi Khuda is a bollywood term.
