What is the ruling on reading and following the tweets and writings of atheists, and what are the consequences of that, such as doubt in the existence of God? And will a person be held accountable for what he read or believed during that period due to curiosity and stress? And what is incumbent upon one who favored a tweet containing mockery of prophets or companions?

Praise be to Allah for your guidance and your distancing yourself from reading abominable things. Avoid everything that might lead you back to these迷误 (deviations), for hearts are weak and doubts are snatchers. Since you have repented and regretted what has passed, nothing more is required of you. Adhere firmly to the Sharia of Allah, safeguard the obligatory prayers, increase in supererogatory acts, remembrance [of Allah], and supplication, and strive diligently in seeking Islamic knowledge. Praise Allah for guidance and remove the stress, for you have turned to a Lord Who is Merciful and Generous.
