An excerpt from the lyrics for a song called "Mountains of Makkah" sung by Zain Bhikha
Oh Mountains of Makkah, Bear witness that I
To the oneness of Allah do I testify
For all that He’s given me, how can I deny
My purpose in life should be only to cry:
I can't understand why there are two I's in that sentence. Of course, we need that first I as the subject for the sentence, but the second I just seems out of place to me.
