Whenever the Prophet (ﷺ) intended to proceed on a journey, he used to draw lots amongst his wives and would take the one upon whom the lot fell. Once, before setting out for Jihad, he drew lots amongst us and the lot came to me; so I went with the Prophet; and that happened after the revelation of the Verse Hijab (i.e. veiling).
Sahih al-Bukhari Book 56, Hadith 94
← Previous Hadith Allah's Messenger (ﷺ) went to the daughter of Milhan and reclined there (and slept) and then (woke up) smiling. She asked, "O Allah's Messenger (ﷺ)! What makes you smile?" He replied, (I dreamt that) some people amongst my followers were sailing on the green sea in Allah's Cause, resembling kings on thrones." She said, "O Allah's Messenger (ﷺ)! Invoke Allah to make me one of them." He said, "O Allah! Let her be one of them." Then he (slept again and woke up and) smiled. She asked him the same question and he gave the same reply. She said, "Invoke Allah to make me one of them." He replied, ''You will be amongst the first group of them; you will not be amongst the last." Later on she married 'Ubada bin As-Samit and then she sailed on the sea with bint Qaraza, Mu'awiya's wife (for Jihad). On her return, she mounted her riding animal, which threw her down breaking her neck, and she died on falling down.

Sahih al-Bukhari Book 56, Hadith 93 Next Hadith → On the day (of the battle) of Uhad when (some) people retreated and left the Prophet, I saw `Aisha bint Abu Bakr and Um Sulaim, with their robes tucked up so that the bangles around their ankles were visible hurrying with their water skins (in another narration it is said, "carrying the water skins on their backs"). Then they would pour the water in the mouths of the people, and return to fill the water skins again and came back again to pour water in the mouths of the people.
