Abu Ruhm, one of the Companions of the Messenger of Allah (ﷺ) who had offered his allegiance to the Prophet under the Tree [i.e. at Hudaybiyya] was heard to say, "I went on the expedition to Tabuk with the Messenger of Allah (ﷺ). While we were travelling at night at al-Akhdar, I was near to the Prophet. A deep sleepiness overcame us, but I began to wake up when my camel wandered near to the Prophet's camel. I was worried that when it came close, it would his foot in the stirrup. I began to pull my camel back, but at a certain point in the night I feel asleep. Then my camel jostled against the camel of the Messenger of Allah (ﷺ) while his foot was in stirrup, hitting his foot. I did not wake up until he exclaimed, 'Ow!' I said, 'Messenger of Allah, ask for forgiveness for me!' The Messenger of Allah (ﷺ) said, 'Never mind.'
