The Salafis are saying that there are words of shirk in Qasidah Burdah, hence it is not permissible to recite it.

Answer

Qasidah Burdah is a qaseedah (song/poetry) in which the author expresses his spiritual love for Allah Ta'ala and His Rasool (sallallahu alayhi wasallam). Qasidah Burdah is not a thikr or an act of Ibaadat. It has no Shar'i significance. It is just a qaseedah as are all other good qaseedahs/nazams. The words quoted by you are not shirk. The supplication is directed to Allah Ta'ala. The word: 'Rabbi' means: 'O My Rabb!'.

The khanaqas where Qasidah Burdah o r o the r q ase edahs are systematically sung are in error. They have lost the Path of Islaah. They are unaware of the goals of a Khaanqah, hence they indulge in trivialities which ultimately culminate into hard-core bid'ah. Instead of reciting the Qasidah as an act of 'ibaadat', they should rather recite the Qur'aan Majeed or engage in Durood or any other form of real Thikrullaah.
