What happens to human bodies after death and at the Resurrection, and will their bodies remain as they are in Paradise and Hellfire, or will they be given other bodies?

Belief in the Last Day is a branch of belief in God, His power, and His justice. Therefore, a disbeliever is first called to believe in God, and then matters of the Hereafter are discussed. Details regarding the conditions of bodies have not been explicitly stated, and one may refer to books such as "Al-Qiyamah al-Sughra wa al-Kubra" (The Minor and Major Resurrections) and "Al-Jannah wa al-Nar" (Paradise and Hellfire) by Omar Sulaiman al-Ashqar, and "Al-Ruh" (The Soul) by Ibn al-Qayyim. A Muslim should not befriend a non-Muslim, as indicated by the hadith: "Do not befriend anyone but a believer." However, one must treat them kindly and invite them to Islam by explaining the virtues of the religion and the proofs of prophethood.
