She heard the Prophet ﷺ say, "The first army from my nation to wage war by sea will have secured their reward."Umm Haram said, I asked, "Messenger of Allah, will I be among them?"He replied, "You will be among them."Then the Prophet ﷺ said, "The first army from my nation to invade the city of Caesar will be forgiven."I asked, "Will I be among them, Messenger of Allah?"He answered, "No."
أنها سمعت النبي ﷺ يقول: أول جيش من أمتي يغزون البحر قد أوجبوا. قالت أم حرام: قلت: يا رسول الله أنا فيهم؟ قال: أنت فيهم. ثم قال النبي ﷺ: أول جيش من أمتي يغزون مدينة قيصر مغفور لهم. فقلت: أنا فيهم يا رسول الله؟ قال: لا.
Bukhari narrated it in the Book of Jihad and Expeditions (2924), from Ishaq bin Yazid Dimashqi, who said, "Yahya bin Hamza narrated to us, Thawr bin Yazid narrated to me, from Khalid bin Madan, that Umayr bin Aswad Ansi told him that he came to Ubada bin Samit while he was staying in the courtyard of Hims, in a building of his, with Umm Haram present with him." Umayr said, "Umm Haram narrated to us," and he then mentioned the hadith.His words, "the city of Caesar," refer to Constantinople. The first to raid it was Yazid bin Muawiya, in the year 52 AH.
