The corresponding expression in Turkish is as follows:
"The Mahdi will not make mistakes / do no wrong. For an angel who does not appear to him (inspiration) always directs him to the truth (right and truth) " (see al-Futuhat al-Makkiye, 3 / 327-366, pb)
That is to say, Hz. Thanks to this inspiration, Mahdi has "infallible heart, unbelievable word" in the lessons of the Qur'anic truths he has given in the method of service he followed . It is the work of this inspiration that " does not mislead ."
