Mishkat al-Masabih 19 Jihad كتاب الجهاد 149

عَن جَابر قَالَ: قَالَ رَجُلٌ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ أُحُدٍ: أَرَأَيْتَ إِنْ قُتِلْتُ فَأَيْنَ أَنَا؟ قَالَ: «فِي الْجنَّة» فَألْقى ثَمَرَات فِي يَده ثمَّ قَاتل حَتَّى قتل

Jabir told that a man said to the Prophet at the battle of Uhud, “Tell me where I shall be if I am killed,” and that when he replied that he would be in paradise he threw away some dates he had in his hand and fought till he was killed. (Bukhari and Muslim.)
