Hudbah ibn Khālid narrated to us; Hammām narrated to us; Qatādah narrated to us; from Anas ibn Mālik,

from Mālik ibn Ṣa'ṣa'ah, that: The Messenger of Allah ﷺ told them about the Night Journey (Isrāʾ) until he reached the fifth heaven, where there was Hārūn (Aaron). He said: “This is Hārūn, so greet him.” So, I greeted him, and he returned the greeting and said: “Welcome to the righteous brother and the righteous Prophet.”

This narration was also reported by Thābit and 'Abbād ibn Abī 'Alī from Anas from the Prophet ﷺ.
