[2252] These are Kaʿb Ibn Mālik, Hilāl Ibn Umayyah and Murārah Ibn al-Rabīʿ, who were sincere Companions but, for one reason or another and without valid excuses, failed to join the Messenger (ﷺ) in his campaign. When he came back, they did not fabricate alibis like the hypocrites did but told the outright truth. To punish them, the Messenger imposed a ban on them; he forbade people to talk to them and ordered them to stay away from their wives. This state of affairs lasted for fifty nights until this aya came down. During this time, they endured acute mental anguish, being both sincere and ostracized by the society to which they belonged. This aya beautifully encapsulates how constrained they felt. For a very detailed firsthand account of their story see al-Bukhārī: 4418 and Muslim: 2769.
