A Kind Gesture on Hazrat Ka'b (ra) bin Malik's Forgiveness
Among those who remained behind from travelling for the Battle of Tabuk was Hazrat Ka‘b (ra) bin Malik. Consequently, he was boycotted and after 40 days, Allah the Almighty accepted his repentance and announced his forgiveness. When he came to the mosque to present himself before the Holy Prophet (sa), it was Hazrat Talha (ra) who came forward and met Hazrat Ka‘b (ra) bin Malik and congratulated him. Apart from Hazrat Talha (ra), no one else stood up from the gathering and Hazrat Ka‘b (ra) stated that he would never forget this kind gesture of Hazrat Talha (ra).
