Sayyiduna Imran bin Husayn (may Allah be pleased with him) says: We were with the Messenger of Allah (peace and blessings be upon him) on a journey, and a woman of the Ansar was riding a she-camel; she was scolding it and cursing it. He (peace and blessings be upon him) said: "Unload her and leave her bare, for she has been cursed." The narrator says: So no one would give her a place.
(b) Hammad bin Zayd narrates from Ayyub that he (peace and blessings be upon him) said: "Take (the load) off her, for she is cursed." So they took it off her. Sayyiduna Imran (may Allah be pleased with him) says: It is as if I can see that she-camel; she was ash-grey in colour.
