The ruling on repeating certain surahs of the Qur'an and adhkar a specific number of times

Question:
Some people make their daily recitation (Bismillah al-Rahman al-Rahim) 786 times, and they recite al-Waqi'ah 42 times, Surah al-Dhariyat 60 times, and Surah Ya-Sin 41 times at the deathbed and otherwise, and they recite in their daily recitation (Ya Latif) 16,641 times. Is this permissible or not?

Answer:
I do not know of any basis for this practice with this specific number. In fact, worshipping Allah by it and believing it to be a sunnah is a religious innovation. Likewise, doing this in this manner at the deathbed, at the time of death, or after death, none of this has a basis in this manner. However, it is prescribed for the believer to recite the Qur'an abundantly, night and day, and to mention Allah (Glorified and Exalted is He) at the beginning of recitation, when eating and drinking, when entering the home, when having intercourse with his wife, and other matters for which the Sunnah has come. It was narrated from the Prophet (peace and blessings be upon him) that he said: .
Likewise, using (Ya Latif, or Ya Allah, or the like) a known number, believing it to be a sunnah, has no basis; rather, it is a religious innovation. However, it is prescribed to supplicate abundantly without a specific number; such as saying: Ya Latif, be merciful to us, or forgive us, or have mercy on us, or guide us, and the like. And likewise, Ya Allah, Ya Rahman, Ya Rahim, Ya Ghafur, Ya Hakim, Ya Aziz, pardon us, help us, and rectify our hearts and our deeds, and the like of that, due to the saying of Allah (Glorified and Exalted is He): [Ghafir: 60], and His saying (peace and blessings be upon him) : [al-Baqarah: 186], but without specifying a number that is not to be exceeded or reduced; except for what has a specified number from the Prophet (peace and blessings be upon him), such as the saying: , one hundred times every day. This is established from the Prophet (peace and blessings be upon him). And likewise, the saying: Subhan Allah wa bihamdihi, one hundred times in the morning and evening.
And likewise: Subhan Allah, alhamdulillah, and Allahu Akbar, thirty-three times after each of the five obligatory prayers, totaling ninety-nine after each prayer, and completing the hundred by saying: La ilaha illa Allah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa 'ala kulli shay'in qadir. All of this is authentic from the Prophet (peace and blessings be upon him).
And likewise, everything that comes in its meaning. And if one recites Surah Ya-Sin or other parts of the Qur'an for the dying person before he dies, there is no harm in it; and it was narrated from the Prophet (peace and blessings be upon him) what indicates this. It is recommended to teach him La ilaha illa Allah until he concludes with it; due to the saying of the Prophet (peace and blessings be upon him): , narrated by Muslim in his Sahih. The intended meaning of "the dead" here is the dying, according to the most correct of the scholars' opinions, and because they are the ones who benefit from being taught.
