Hadith Section/Book: Sahih Bukhari Sahih Bukhari Book 52. Fighting for the Cause of Allah (Jihaad)
Narated By Anas bin Malik : Um Haram said, "Once the Prophet slept in my house near to me and got up smiling. I said, 'What makes you smile?' He replied, 'Some of my followers who (i.e. in a dream) were presented to me sailing on this green sea like kings on thrones.' I said, 'O Allah's Apostle! Invoke Allah to make me one of them." So the Prophet invoked Allah for her and went to sleep again. He did the same (i.e. got up and told his dream) and Um Haran repeated her question and he gave the same reply. She said, "Invoke Allah to make me one of them." He said, "You are among the first batch." Later on it happened that she went out in the company of her husband 'Ubada bin As-Samit who went for Jihad and it was the first time the Muslims undertook a naval expedition led by Mu awiya. When the expedition came to an end and they were returning to Sham, a riding animal was presented to her to ride, but the animal let her fall and thus she died.
