I have not come across “catch me,” but I have read “help.” I was not certain that it would be shirk, I had doubts and it was because while I understand Rasool SAW will be a waseela…i was iffy about a dua that asks other than Allah for help; that was all. It is true that we ask teachers and parents etc for help. But dua is often made for things that are not so easily granted by people..and so we ask of Allah. This was the doubt behind my question; that is all.
