I heard Ka`b b. Malik - the transmitter Ibn al-Sarh then narrated the story of his remaining behind from the Prophet (ﷺ) during the campaign of Tabuk - say: The Messenger of Allah (ﷺ) forbade the Muslims to speak to any of us three. When (in this state) Abundant time passed on me, I ascended the wall of the garden of Abu Qatadah who was my cousin. I saluted him, but, I swear by Allah, he did not return salute to me. He then narrated the story of the revelation of the Qur'anic verses relating to his repentance.
