Ummu Harām binti Milhān mendengar Rasulullah ﷺ bersabda, "Tentera pertama daripada umatku yang belayar di laut telah menjamin diri mereka (dengan Syurga)." Ummu Harām bertanya, "Wahai Rasulullah, adakah saya termasuk dalam kalangan mereka?" Baginda ﷺ menjawab, "Engkau termasuk dalam kalangan mereka." Kemudian, Baginda ﷺ bersabda, "Tentera pertama daripada umatku yang berperang menuju ke Kota Kaisar (Konstantinopel) akan diampunkan." Dia bertanya, "Adakah saya termasuk dalam kalangan mereka, wahai Rasulullah?" Baginda ﷺ menjawab, "Tidak." 306 Pada zaman pemerintahan Mu‘āwiyah, Ummu Harām turut serta dalam armada tentera laut Islam yang pertama, menemani suaminya, dan wafat ketika terjatuh dari tunggangannya di wilayah musuh.307

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 dan yang lain-lain meriwayatkan bahawa tempat makamnya di Pulau Cyprus telah diketahui.308 Ibn Ḥajar berkata, Ini mengandungi beberapa ramalan oleh Nabi ﷺ tentang perkara yang akan berlaku, dan semuanya berlaku sebagaimana yang baginda sabdakan, lalu ia dianggap termasuk antara tanda-tanda kenabiannya. Antaranya ialah bahawa umatnya akan kekal selepas baginda, dan bahawa di kalangan mereka akan ada orang-orang yang kuat, digeruni, dan menjadi kekuatan yang berpengaruh terhadap musuh, dan bahawa mereka akan menakluki wilayah-wilayah sehingga tentera menunggang di atas laut, dan bahawa Umm Ḥarām akan hidup sehingga masa itu, dan bahawa dia akan bersama tentera yang menunggang di atas laut itu, dan bahawa dia tidak akan sempat menyaksikan kempen ketenteraan yang kedua [ke Constantinople].309

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
