What is the Hadith that refers to the noble verses which Ibn Qudamah used to recite after the Fajr prayer, and what is the authenticity of this Hadith, and does its weakness fall under the category of the permissibility of acting upon a weak Hadith?

Relying on the experiences of the righteous regarding the properties of the Qur’an is not sufficient to establish a legal ruling; rather, a legal basis from the Qur’an and Sunnah is necessary. Gathering specific verses and dedicating them to recitation, such as the verses of protection (Ayat al-Hirs), is an innovation that has no basis. What Abu Umar ibn Qudamah did by reciting specific verses was his own ijtihad (independent reasoning); a Sunnah is not established thereby, nor can it be used as a proof. The proof lies in what has been authentically reported from the Prophet, peace and blessings be upon him. Scholars have not unanimously agreed on the permissibility of acting upon a weak hadith unconditionally. Those who permit it have stipulated conditions, such as that it should not be severely weak and that its authenticity should not be believed.
