What is the ruling on watching videos refuting atheists and Christians, while falling into doubts and suspicions that amount to obsessive whisperings regarding the source of scientific miracles in the Qur’an?

An atheist exposed to specious arguments is advised to read the Glorious Qur'an and its concise commentaries, and to reflect upon its verses; for the Qur'an engenders certainty and purifies hearts from specious arguments. One must be wary of listening to specious arguments, as the Salaf (pious predecessors) warned against them, believing that hearts are weak and specious arguments are captivating. One can benefit from websites such as "Rawasekh" and "Al-Muhawir li al-Radd 'ala al-Shubuhat" for discussing specious arguments.
