Having worked with many people from India and Pakistan in the 1990s, I was often fascinated by words that sounded Arabic in origin. When asking about the meaning, they were indeed Arabic. And I could detect more words in the few Hindi Bollywood movies that I have seen as well.
Arabic influence on Hindi may have been via several avenues. One was via Farsi (Persian) as an intermediate, having been the language of the court for the Mughal emperors. Another was through Muslim scholars using these words from Arabic texts and they made their way into the vernacular.
