Musannaf Ibn Abi Shayba 33:501

Ibn Fudayl narrated to us, from Husayn, from al-Sha'bi, from al-Nu'man ibn Bashir, who said: Abdullah ibn Rawahah fainted, and his sister, 'Amrah, began to weep and say, "O my brother!" and "O such and such!" listing his virtues over him. When he regained consciousness, Ibn Rawahah said, "I did not say anything [in my state of unconsciousness] except that it was said to me, 'Are you indeed such?'"
