Tariq bin Shihab narrated: When Umar (may Allah be pleased with him) was martyred, Umm Ayman (may Allah be pleased with her) said: "Today Islam has become weak." The narrator said: Sufyan would sometimes say in the hadith of Qais: They said to her (Umm Ayman): Do not weep. She replied: I weep over the news from the sky. Ishaq (the narrator) said: We consider this from Sufyan to be a mistake.
