{ Indeed if the hypocrites, and those with sickness in their hearts, and those who spread lies in Medina, do not cease, surely We will incite you against them, then they will only be your neighbors there a little longer. They are cursed; wherever they can be reached, they will be taken and fiercely killed. The way of Allah for those who came before; and you will not find the way of Allah to be altered } Al-ahzab 60-62

{ And those with sickness in their hearts } : people who were weak in belief and scarcely able to remain firm in it; it is also said that these are those who adulterate and those given to prostitution, from the word of the Most High: { Such that those with sickness in their hearts might desire } [Al-ahzab 32]. { And those who spread lies } : people who would spread bad reports about the Messenger of Allah’s (SAW) troops, saying that they had been defeated and killed and that such and such had befallen them – breaking the hearts of the Believers.
