The Supplication for Completing the Recitation of the Qur'an and a Specific Prayer for Memorizing It, and the Distribution of Mushafs

Question:
The brother questioner who did not mention his name in this message says: Honorable Shaykh, we memorize the Qur'an in schools, and there is a supplication recited after we have memorized the entire Qur'an. We make this supplication in a prayer of four rak'ahs: in the first, we recite Surah Ya-Sin after al-Fatihah; in the second, Surah al-Dukhan; in the third, Surah al-Sajdah; and in the fourth, Surah Tabaarak. Then the supplication is recited at the end, before the taslim. Is this supplication authentic, since I read that it was reported in al-Tirmidhi with a hasan chain from Ibn 'Abbas? And Honorable Shaykh, if I distribute mushafs with this supplication at the end, have I spread a bid'ah (religious innovation), and am I required to take this written text?

Answer:
This practice has no basis. There is no specific prayer or supplication for completing the recitation of the Qur'an or for memorizing it. All of this is a religious innovation (bid'ah). The distribution of mushafs is not specific to those who complete the recitation of the Qur'an. Mushafs should be distributed at any time, even if one has not completed the recitation of the Qur'an. Distributing mushafs is part of spreading knowledge and spreading the Book of Allah the Exalted, and it is not specific to the occasion of completing the recitation of the Qur'an. Yes.

May Allah reward you with good.
