Mishkat al-Masabih

Jabir reported God's messenger as saying, "I entered paradise and met ar-Rumaisa', the wife of Abu Talha. Hearing a movement, I asked who it was and was told that it was Bilal. I saw a palace with a girl in the courtyard and when I asked whose palace it was, I was told that it belonged to `Umar b. al-Khattab. I wanted to enter and look at it, but I remembered your jealous nature." `Umar replied, "Messenger of God for whom I would give my father and mother as ransom, could I be jealous of you?" (Bukhari and Muslim.)
