Musnad Abu Ya'la al-Mawsili 110:134

Ibrahim ibn al-Hajjaj al-Sami narrated to us, Muhammad ibn Thabit al-'Abdi narrated to us, Jabalah ibn 'Atiyyah narrated to us, from Ishaq ibn 'Abd Allah, from Ibn 'Abbas, who said: While the Messenger of Allah (may Allah bless him and grant him peace) was in the house of one of his wives, he placed his head on the thigh of one of them and dozed off. Then he laughed in his sleep. After I saw him, some of the people of the house asked him, saying: "O Messenger of Allah, what made you laugh?" He said: "I was amazed at people from my nation who ride this sea, with the terror of the enemy, striving in the path [of Allah]." He mentioned to them a virtue that Muhammad did not memorize. A woman who was there said: "O Messenger of Allah, pray to Allah that He makes me one of them." So he prayed for her. Her husband went out with her on a military expedition. While she was on the seashore, traveling on her mount, she fell, and her thigh was broken, and she died.
