What is the solution to quickly reach certainty and get rid of doubts and questions about religion, and is it sufficient to ignore these doubts and adhere to acts of worship for a person to be a believer in the sight of Allah?

We advise the questioner to ignore these questions and focus on strengthening his faith by seeking Allah’s help, frequently remembering Him, reciting His Book, persistently supplicating, seeking forgiveness, and acquiring beneficial knowledge. He should start by reading accessible books such as Tafsir (definition) al-Sa'di and the 'Aqidah series by Omar al-Ashqar. If a matter becomes unclear to him, he should ask about it without delving deeply into specious arguments. He should also steer clear of the books of opponents and disputants, as well as books on philosophy and atheism.
