Translation
O God, my God! I call Thee, Thy Prophets and Thy Messengers, Thy Saints and Thy Holy Ones, to witness that I have declared conclusively Thy Proofs unto Thy loved ones and set forth clearly all things unto them, that they may watch over Thy Faith, guard Thy Straight Path and protect Thy Resplendent Law. Thou art, verily, the All-Knowing, the All-Wise!
