Sunan an-Nasa'i, Volume 4, Book 25, Hadith 3156 (DarusSalam) ⓘ

It was narrated that 'Amr said: "I heard Jabir say: 'A man said on the day of Uhud: If I am killed in the cause of Allah, where do you think I will be? He said: In Paradise. He threw down some dates that were in his hand and fought until he was killed.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، قَالَ سَمِعْتُ جَابِرًا، يَقُولُ قَالَ رَجُلٌ يَوْمَ أُحُدٍ أَرَأَيْتَ إِنْ قُتِلْتُ فِي سَبِيلِ اللَّهِ فَأَيْنَ أَنَا قَالَ ‏ "‏ فِي الْجَنَّةِ ‏" ‏ ‏.‏ فَأَلْقَى تَمَرَاتٍ فِي يَدِهِ ثُمَّ قَاتَلَ حَتَّى قُتِلَ ‏.‏
