What is the religiously agreed-upon nature of Satan, and is man singular or dual?

If the questioner is asking about the original creation of Satan, then he was created from fire, as Allah Almighty says: "You created me from fire and created him from clay." The relationship between humans and Satan is a continuous struggle and challenge since the beginning of creation, as Satan vowed to mislead the children of Adam. However, his authority is weak over believing, trusting individuals. The Muslim is independent and free, and Allah has granted him the ability to distinguish between good and evil. To be protected from Satan, a Muslim must adhere to the Qur'an and Sunnah, maintain remembrance of Allah (dhikr), and frequently mention Allah, for when Allah is mentioned, Satan retreats and distances himself.
