In the fifth (47) verse, it was explained that the hypocrites had procured the permission to stay away from Jihad by deceit and now it was better that they just did not participate in it. Had they gone there, they would have done nothing but hatch conspiracies, circulate rumors and spread disorder. The Qur'anic statement: وَفِيكُمْ سَمَّاعُونَ لَهُمْ (And among you there are their listeners) means that, among Muslims, there were some simple people too, people who could be easily taken advantage of and who may have likely been affected by their false rumors.
