Musnad Abu Ya'la al-Mawsili 147:1

Abu Nasr ‘Abd al-Malik ibn ‘Abd al-‘Aziz al-Qushayri al-Tammar narrated to us, Hammad ibn Salamah narrated to us, from Abu ‘Imran al-Jawni, from Anas ibn Malik, who said: The Messenger of Allah (ﷺ) said: "I entered Paradise, and there I was at a palace of gold. I said: 'To whom does this palace belong?' They said: 'To a young man from Quraysh.' I thought it was for me, so I said: 'Who is he?' They said: 'Umar ibn al-Khattab.' O Abu Hafs, were it not for what I know of your protective jealousy (ghayrah), I would have entered it." He (Umar) said: "O Messenger of Allah, as for those over whom I have protective jealousy, I would never have protective jealousy over you."
