Narrated Anas bin Malik
Whenever Allah's Messenger (ﷺ) went to Quba, he used to visit Um Haram bint Milhan who would offer him meals; and she was the wife of 'Ubada bin As-samit. One day he went to her house and she offered him a meal, and after that he slept, and then woke up smiling. She (Um Haram) said, "I asked him, 'What makes you laugh, O Allah's Messenger (ﷺ)?' He said, 'Some people of my followers were displayed before me as warriors fighting for Allah's Cause and sailing over this sea, kings on thrones,' or said, 'like kings on thrones.' (The narrator, 'Is-haq is in doubt about it.) I (Um Haram) said, 'O Allah's Apostle! Invoke Allah that He may make me one of them.' He invoked (Allah) for her and then lay his head and slept again and then woke up smiling. I asked, 'What makes you laugh, O Allah's Messenger (ﷺ)?' He said, 'Some people of my followers were displayed before me as warriors fighting for Allah's Cause and sailing over this sea, kings on the thrones,' or said, 'like kings on the thrones.' I (Um Haram) said, 'O Allah's Messenger (ﷺ)! Invoke Allah that He may make me one of them.' He said, You will be amongst the first ones." It is said that Um Haram sailed over the sea at the time of Muawiya, and on coming out of the sea, she fell down from her riding animal and died.
