Riḍwān (or Rızvan , ar|رضوان), is an angel in Islam, who guards the gates of heaven. The word Ridwan meaning pleasure of Allah, is mentioned in the Quran in Surah maidah verse 16. "Riḍwān", in: Encyclopaedia of Islam, Second Edition, Edited by: P. Bearman, Th. Bianquis, C. E. Bosworth, E. van Donzel, W. P. Heinrichs. Consulted online on 16 October 2019[1] [2] He namely appears in later reports and Mi'raj narration.[3] 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 concealed Iblis in his mouth, carrying him past the guardian.[4] His name probably developed from the Quranic term riḍwan. However, in the Quranic usage, it does not refer to an angel.[5]
