Then she continued:

O people of Kufa, who deceive, forsake and contrive, it is you who weep. May Allah not halt your tears and may your chests burn incessantly with the fire of grief and sorrow. Your example is that of a woman who assiduously prepares a strong rope and then un- twines it herself, wasting her own hard labour.”

“You swear such false oaths, which bear no truthfulness at all. Beware that you have nothing except vain talk, false pride, mischief, malice, evil, rancour, falsehood, and sycophancy. Beware that your position is that of slave- maids and purchased girls who are but the meanest beings.”

“Your hearts are full of enmity and rancour. You are like the vegetation that grows on filthy soil and is yet green, or like the mortar applied unto graves.”

“You should know that you have perpetrated a very morbid deed and this has prepared an evil provision for your next life, because of which, Allah’s anger is against you and His wrath would fall upon you.”
