What is the supplication a Muslim recites before beginning to memorize the Qur'an?

There is no specific supplication before starting to memorize the Qur’an. However, it is prescribed to seek refuge with Allah from Satan, the accursed, before recitation in general, as in His Almighty saying: "So when you recite the Qur'an, [first] seek refuge in Allah from Satan, the expelled [from His mercy]." As for supplication for memorizing and firming the Qur’an, a long supplication was mentioned in Sunan al-Tirmidhi, but al-Dhahabi considers it fabricated.
