Tariq bin Shihab (may Allah have mercy on him) said: When the Messenger of Allah (peace and blessings be upon him) passed away, Sayyidah Umm Ayman (may Allah be pleased with her), who was the mother of Usamah bin Zayd, began to weep. She was asked: Why are you weeping? She said: "The news from the heavens has been cut off from us."
