Humaid said: "Anas was asked: “Did the Prophet (ﷺ) use a ring?' He said: “Yes. One night he delayed the later 'Isha' prayer, until almost halfway through the night. When he prayed the Prophet (ﷺ) turned his face toward us and said: “You are still in a state of prayer so long as you waiting for it.'" Anas said: “It is as if I can see the luster of his ring.' According to the narration of 'Ali - that is, Ibn Hujr - "until halfway through the night””””"
