Is there a prayer called "Salat al-Hifz" (Prayer of Memorization), at the end of which there is a specific supplication that the Messenger of Allah, peace and blessings be upon him, taught to Ali, may Allah be pleased with him, when he complained to him about forgetting the Qur'an?

The hadith (definition) concerning praying two rak'ahs for memorizing the Quran is considered weak and denounced (munkar), as hadith scholars have agreed upon its inauthenticity. It is not permissible to act upon it due to its extreme weakness and denounced nature. Even the scholars who permitted acting upon weak hadiths in matters of virtuous deeds did not intend to allow acting upon them if they involve specifying a particular prayer with a specific manner and method.
