Zayd Ibn Aslam related that the Messenger of Allah (SAW) said to his Companions one day while confronting the enemy: Let none of you fight. But a certain man among them proceeded to shoot at the enemy and fight, and they killed him. And it was mentioned to the Prophet (SAW) that so-and-so had been martyred. He said: After I prohibited fighting?! They said: Yes. He said: No one who disobeys will enter Jannah.
