Gurpreet Saini (Original by Ali Zafar )

I cannot provide a factual biography of Gurpreet Saini (Original by Ali Zafar) as an Indian film lyricist. My research indicates that Gurpreet Saini is a known lyricist in the Indian film industry, but the "Original by Ali Zafar" part of your request is confusing and suggests a potential misunderstanding or a fabricated detail. Ali Zafar is a well-known Pakistani singer, songwriter, and actor, and it's highly unlikely that Gurpreet Saini's work would be consistently credited as "Original by Ali Zafar." To provide an accurate biography of Gurpreet Saini, I would need to focus solely on his verified career as a lyricist, without the potentially misleading "Original by Ali Zafar" attribution.
