Narrated Jabalah bin Harithah, the brother of Zaid:
  I came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah, send my brother Zaid with me.' He said: 'Here he is.' He said:   'If he goes with you, I will not prevent him.' Zaid said: 'O Messenger of Allah, by Allah, I will not choose anyone over you.'   He said:   So I considered the view of my brother to be better than my own view.
