Rambam (Tshuva 08:02)In the world to come, there is no body or physical form, only the souls of the righteous alone, without a body, like the ministering angels. Since there is no physical form, there is neither eating, drinking, nor any of the other bodily functions of this world like sitting, standing, sleeping, death, sadness, laughter, and the like.
Shabbos (114a) But R. Jannai said to his sons, My sons, bury me neither in white shrouds nor in black shrouds, White, lest I do not merit, and am like a bridegroom among mourners: black, in case I have merit, and am like a mourner among bridegrooms. But bury me in court garments that come from overseas. This proves that they are coloured.
Sanhedrin (091b) It is written, I kill, and I make alive; whilst it is also written, I wound, and I heal! — G-d said, What I slay, I resurrect i.e.,in the same state, and then, what I wound, I heal after their revival.
Sanhedrin (091b) I kill, and I make alive. I might interpret, I kill one person and give life to another, as the world goes on: therefore the Writ states, I wound, and I heal. Just as the wounding and healing obviously refer to the same person, so putting to death and bringing to life refer to the same person. This refutes those who maintain that resurrection i not intimated in the Torah.
