All of what the Mukhbir-i sâdiq ‘’alaihi wa ’alâ âlihi-s-salâtu wa-s-salâm’ (he who always tells the truth, the Prophet) communicated about the grave, Rising, Hashr (assembling in the space of Arasât after the Rising), Neshr (dispersing after the settling of accounts to go into Paradise or Hell), and about Paradise and Hell, is true. Believing in the next world, like believing in Allâhu ta’âlâ, is an essential of îmân. He who denies the next world is a kâfir, as if he denied Allâhu ta’âlâ.
