From Sahih Bukhari (Hadith 6770):
Narrated `Aisha:Allah's Messenger (ﷺ) once entered upon me in a very happy mood, with his features glittering with joy, and said, "O `Aisha! won't you see that Mujazziz (a Qa'if) looked just now at Zaid bin Haritha and Usama bin Zaid and said, 'These feet (of Usama and his father) belong to each other." (See Hadith No. 755, Vol)
