The Prophet (ﷺ) ascended the mountain of Uhud and Abu Bakr, `Umar and `Uthman were accompanying him. The mountain gave a shake (i.e. trembled underneath them) . The Prophet (ﷺ) said, “O Uhud ! Be calm.” I think that the Prophet (ﷺ) hit it with his foot, adding, “For upon you there are none but a Prophet, a Siddiq and two martyrs.”
