Which is absolutely the best form of dhikr: reading the Qur’an or repeating “La Ilaha Illallah”?

Scholars have agreed that the Noble Qur’an is the best form of remembrance (dhikr), as stated by Sufyan al-Thawri and Imam al-Nawawi. Nevertheless, combining the virtues of actions, such as reciting the Qur’an and engaging in other forms of dhikr, is superior. Ibn Taymiyyah pointed out that what is virtuous in its specific place is better than what is absolutely virtuous. Thus, glorifying Allah (tasbeeh) during bowing (ruku') and prostration (sujood) is better than reciting thean Qur’an during them. Ibn ‘Uthaymeen clarified that what is less virtuous (mafdool) may become more virtuous than what is inherently virtuous (fadil) in certain situations, such as responding to the muezzin instead of continuing to recite the Qur’an. Ibn Baz mentioned that the prescribed regular supplications (awrad) at the beginning and end of the day are better than reciting the Qur’an at that specific time, because these supplications are time-bound acts of worship that expire if their time passes, whereas the time for reciting the Qur’an is extensive.
