Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that the Messenger of Allah (peace and blessings be upon him) recited this verse:“Fear Allah as He should be feared, and do not die except as Muslims.”(Aal-e-Imran: 102) Then he said:“If a single drop of Zaqqum were to be dropped into the oceans of the world, it would ruin the lives of all the people of the world, so what will be the state of the person who eats it.”
