Musannaf Ibn Abi Shayba 36:492

Abu Usama narrated to us, from Sufyan, from Qays ibn Muslim, from Tariq ibn Shihab, who said: When the Prophet, may Allah bless him and grant him peace, was taken [passed away], Umm Ayman began to weep. It was said to her, "Why do you weep, O Umm Ayman?" She said, "I weep because the news from the heaven has been cut off from us."
