How should one deal with and respond to atheists, and is there a specific research paper that can be presented to them for the purpose of their guidance (to Islam)?

Dealing with atheists varies depending on the circumstances and individuals, and aims to rescue them from atheism without harming the one who is dealing with them. If this goal cannot be achieved, the original principle is to stay away from them. Responding to them requires knowledge and insight from specialists. As for the suggested books to gift to atheists, they are:

1. The Phenomenon of Criticizing Religion in Modern Philosophy (Sultan Al-Omari).

2. Atheism: Its Means, Its Danger, and Ways to Confront It (Saleh Sindi).

3. The Atheism Militia: An Introduction to Understanding the New Atheism (Abdullah Al-Ujairi).

4. Atheism: The Certainty of Delusion and the Emptiness of Nothingness (Hussam Al-Din Hamid).

5. The Answer: The Quran and Your Existential Questions (Mohab El-Said).
