Battle of Tabuk — the glad tidings to Ka'b ibn Malik at Umm Salama's

غزوة تبوك — تبشير كعب بن مالك عند أم سلمة

At Tabuk, the Prophet ﷺ's last campaign, Ka'b ibn Malik was one of the three hypocrites who stayed behind without excuse until their repentance descended. Waqidi reports the Prophet telling Umm Salama at night that Ka'b's repentance had come down, and that he would not send for them until dawn lest he keep her awake; at morning prayer he announced their repentance to the people.
