Riḍwan (or Riswan) is an angel in Islam, who guards the gates of heaven. He namely appears in Mi'raj narration. Ridwan also plays an important role as the guardian of heaven in the Qisas Al-Anbiya, here he must prevent Iblis from entering the keep of Adam, but was tricked by a serpent, who consealed Iblis in his mouth, carrying him past the guardian. His name probably developed from the Quranictermriḍwan. However, in the Quranic usage, it does not refer to an angel.
