It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) passed away from the effect of the meat which a Jewish woman had poisoned, and his aorta had been severed by that poison exactly one year later, he used to say: "I have continued to feel its effect."
