The Final Prophet by Mohammad Elshinawy

Umm Ḥarām bint Malḥān  heard the Messenger of Allah صلى الله عليه وسلم say, “The first army from my nation to ride the sea have guaranteed themselves [Paradise].” Umm Ḥarām said, “O Messenger of Allah, will I be among them?” He said, “You will be among them.” Later, he صلى الله عليه وسلم said, “The first army from my nation to march in battle to the City of Caesar (Constantinople) will be forgiven.” She said, “Will I be among them, O Messenger of Allah?” He said, “No.”306 During the reign of Mu‘āwiyah , Umm Ḥarām rode in the first Muslim naval fleet, accompanying her husband, and died upon falling off her mount in enemy lands.307

Imam al-Ṭabarānī and others report that the whereabouts of her gravesite on Cyprus Island were known.308 Ibn Ḥajar said, This contains multiple prophecies by the Prophet صلى الله عليه وسلم of what would take place, and it all occurred just as he said, and hence is considered among the signs of his prophethood. Of them is that his nation would remain after him, and that among them are those who would be strong, formidable, and a consequential force against the enemy, and that they would conquer territories until the army rides the sea, and that Umm Ḥarām would live until that time, and that she would be with that army that rode the sea, and that she would not live to see the second military campaign [to Constantinople].309
