۞ وَأَمَّا ٱلَّذِينَ سُعِدُوا۟ فَفِى ٱلْجَنَّةِ خَٰلِدِينَ فِيهَا مَا دَامَتِ ٱلسَّمَٰوَٰتُ وَٱلْأَرْضُ إِلَّا مَا شَآءَ رَبُّكَ ۖ عَطَآءً غَيْرَ مَجْذُوذٍۢ
And as for those who will be glad (that day) they will be in the Garden, abiding there so long as the heavens and the earth endure save for that which thy Lord willeth: a gift unfailing.

Sahih al-Bukhari
Fighting for the Cause of Allah (Jihaad)
Chapter: The superiority of him who goes in Allah's Cause and dies on the way
Narrated Anas bin Malik:
Um Haram said, "Once the Prophet (ﷺ) 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 Messenger (ﷺ)! Invoke Allah to make me one of them." So the Prophet (ﷺ) 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.
