Beautiful Lines are Mehfuz
Jab se tujhe bhulane ki kasam khayi hain
Aur pehle se bhi zyaada teri yaad aayi hain
Ever since the day I've taken an oath of forgetting you
I keep on remembering you even more than ever
These lines appear in the song Bewafa from Euphoria's album Mehfuz. Thanks for the information, Udit.
Mehfuz is an Urdu word that means secret, secure, and safe guarded.
A technical example, thought of this on the spur of the moment, would be—HTTPS is a mehfuz protocol that encrypts data. :-)
