Gate No. 31 (Hud Gate)

The gates of the Prophet's Mosque have been systematically numbered during modern expansion periods. Each gate takes its name from either a historical companion, a caliph, or a Saudi ruler. The Hud Gate bears the name of the prophet Hud, who was sent to the people of 'Aad. [Source: "The Prophet's Mosque", TDV Islamic Encyclopedia, https://islamansiklopedisi.org.tr/mescid-i-nebevi]
