What is the ruling on reciting specific surahs, such as "Al-Mulk," "Ad-Dukhan," and "Ya-Sin," at particular times, based on the belief that they bring about certain virtues, and are these actions considered innovations (bidʻah)?

Reciting Surat Al-Mulk every night is a confirmed Sunnah from the Prophet, peace and blessings be upon him. However, regarding the recitation of Yasin and Al-Dukhan every night, no authentic text has been established concerning it. Nevertheless, there is no harm in reciting them regularly, as their recitation is permissible in principle. Many scholars have consistently recited them and did not consider it an innovation.
