Is the prayer of tasbih a religious innovation?

Question:
From the United Arab Emirates, Sister Aisha Abdul Qadir sent a message asking your Eminence, saying: I heard that there is a prayer called the prayer of tasbih, and that the one who performs this recommended practice receives a great reward and forgiveness for sins. I read evidence for this from what was reported from the Messenger (peace and blessings be upon him), but some people say that it is a religious innovation; so I hope your Eminence will clarify the correctness of the statement. May Allah reward you with good?

Answer:
The correct view regarding the prayer of tasbih is that it is not established and not prescribed, and its hadith is weak from all its routes; so it is not befitting for the believer to practice it. Even though some of our brothers among the students of knowledge have authenticated it, the correct view is that it is weak and not authentic. Its hadith is weak, anomalous, and denounced, and it contradicts the evidence of the Shari'ah; so it is not permissible to practice it, nor to call people to it, nor to believe that it is a recommended practice. Rather, it is a religious innovation that contradicts the authentic hadiths and contradicts what Allah (Glorified and Exalted is He) has legislated .
