Regarding the vision of the Messenger of Allah ﷺ concerning Abu Bakr and Umar, he said, "I saw the people gathered together, and Abu Bakr stood up and drew one or two buckets of water, but there was weakness in his drawing, and may Allah forgive him. Then Ibn al-Khattab stood up, and the bucket turned into a large one in his hands. I have never seen an extraordinary man among the people performing such a feat as he did, until the people had watered their camels and made them kneel at their resting place."
حدثنا عفان حدثنا وهيب حدثنا موسى بن عقبة حدثني سالم
عن رؤيا رسول الله ﷺ في أبي بكر وعمر قال رأيت الناس اجتمعوا فقام أبو بكر فنزع ذنوبا أو ذنوبين وفي نزعه ضعف والله يغفر له ثم قام ابن الخطاب فاستحالت غربا فما رأيت عبقريا من الناس يفري فريه حتى ضرب الناس بعطن
Its isnad is sahih, and it is a repetition of 5629. Al-atan, with a fatha on the ain and the ta, both unvoweled letters, and ending in a nun, means the resting place of camels around water.
