Language, especially in poetry and rap, works through metaphor. When someone says, “Rabb ne baazu pharya hai,” no one in the culture understands it as God having a physical arm. It is an established idiom for support, protection, and divine backing.The rule of thumb is this that the words are understood according to their common usage (Urf) and intended meaning, not their literal dictionary definition. If a phrase is universally understood as a metaphor, it remains a metaphor. It doesn’t become problematic just because a literal interpretation would be physically impossible.Even the Quran uses human language to describe the Divine because that is the only language we have. For example, the Quran mentions the “Hand of Allah” (Yadullah) or God “Sitting on the Throne” (Istawa).
If religious texts use these metaphors to bring the Divine closer to our understanding, it is logically consistent for a poet or rapper to use similar imagery to express their personal reliance on God.
The use of figurative language is fine as long as the intent and belief behind it are sound. It would only become a concern if the lyric intentionally tries to humanize God in a literal, theological sense, the tone becomes so casual or “street” that it strips away the respect due to the Creator, the lyric attributes God’s specific powers to a human being in an arrogant or literal way.
In your specific example, the meaning is actually quite spiritual—it’s about Tawakkul (trust in God) despite what the “world” thinks. The singer is saying they don’t care about the world because they feel God’s support. This is a positive sentiment.
