What is the ruling on a song that includes the phrase: "O nights of joy, return and free me from my bonds, for I no longer know any meaning for existence; save me, wipe away these tears from my cheeks"? And does this fall under seeking help from other than Allah?

The statement: "O nights of joy, return and free me from my bonds" could potentially be a supplication to Allah for the return of joyous nights, and there is no harm in this, as Allah is the Turner of time. It could also potentially be a supplication to the nights themselves, and this is polytheism (shirk) with Allah because it is seeking aid from other than Allah in a matter that none but He, the Exalted, can accomplish.
