He, sallallaahu ‘alayhi wa sallam, gave them glad tidings of their good end

As in the narration of Anas ibn Maalik: that the Prophet of Allah, sallallaahu ‘alayhi wa sallam, climbed Mount Uhud with Abu Bakr, ‘Umar, and ‘Uthmaan, when it shook. The Prophet of Allah, sallallaahu ‘alayhi wa sallam, said: “Be firm, O Uhud, because there is upon you a Prophet, a Siddeeq [truthful one, i.e. Abu Bakr], and two martyrs ]i.e. ‘Umar and ‘Uthmaan].”
