What did the Prophet Muhammad (saw) do when the mountain of Uhud trembled as he climbed it with Abu Bakr, `Umar and `Uthman?
 Narrated Anas:                     The Prophet 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 said, "O Uhud ! Be calm." I think that the Prophet hit it with his foot, adding, "For upon you there are none but a Prophet, a Siddiq and two martyrs."
