At-Tawbah · 9:47

47. It was a blessing that these hypocrites did not go with them, because if they had gone they would only have increased them in problems: demoralising people and making them doubt, hurrying between their lines, spreading rumours to divide them. Some of the believers would listen to such lies, believing and repeating them, causing arguments amongst them. Allah knows the wrongdoers among the hypocrites, who try to spread conspiracies and doubts among the believers.
