Musnad Ahmad 1176:1

Rawh narrated to us, he said: Hammad—meaning Ibn Salamah—narrated to us, from Yahya ibn Sa’id, from Muhammad ibn Yahya ibn Habban, from Anas ibn Malik, from Umm Haram, that she said: While the Messenger of Allah (peace and blessings of Allah be upon him) was sleeping in my house, he woke up laughing. I said: "May my father and mother be sacrificed for you, what makes you laugh?" He said: "Some people of my nation were presented to me, riding the back of this sea, like kings upon thrones." I said: "Supplicate to Allah to make me one of them." He said: "O Allah, make her one of them." Then he slept again, and woke up laughing. I said: "May my father and mother be sacrificed for you, what makes you laugh?" He said: "Some people of my nation were presented to me, riding this sea, like kings upon thrones." I said: "Supplicate to Allah to make me one of them." He said: "You are among the first ones." She went on a military expedition with ‘Ubadah ibn al-Samit, who was her husband. A grey mule of hers threw her, and she fell and died.
