Sahih al-Bukhari, Volume 5, Book 57, Hadith 49 (USC-MSA) ⓘ

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."

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، أَنَّ أَنَسًا ـ رضى الله عنه ـ حَدَّثَهُمْ قَالَ صَعِدَ النَّبِيُّ صلى الله عليه وسلم أُحُدًا، وَمَعَهُ أَبُو بَكْرٍ وَعُمَرُ وَعُثْمَانُ، فَرَجَفَ وَقَالَ ‏ "‏ اسْكُنْ أُحُدُ ـ أَظُنُّهُ ضَرَبَهُ بِرِجْلِهِ ـ فَلَيْسَ عَلَيْكَ إِلاَّ نَبِيٌّ وَصِدِّيقٌ وَشَهِيدَانِ ‏" ‏‏.‏
