In Islam, the belief is that without guidance—primarily from Allah through the Qur'an and the teachings of the Prophet Muhammad (peace be upon him)—humanity would be lost both in this life and the hereafter. The Qur'an is seen as a source of divine wisdom and a guide for leading a righteous life, while the Hadith (the sayings and actions of the Prophet) further clarify how to implement these teachings.
Guidance from Allah helps believers distinguish between right and wrong, leading to moral, ethical, and spiritual well-being. Without this guidance, many believe that humans would be spiritually lost, leading to eternal consequences in the afterlife, such as being deprived of Jannah (Paradise).
