"There is no soul on Earth that dies, and is in a good position before Allah, that would like to come back to you, even if it had all this world, except the one who is killed (in the cause of Allah); he wishes that he could come back and be killed again." (Using translation from Nasāʾī 3159)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَا عَلَى الْأَرْضِ مِنْ نَفْسٍ تَمُوتُ وَلَهَا عِنْدَ اللهِ خَيْرٌ تُحِبُّ أَنْ تَرْجِعَ إِلَيْكُمْ إِلَّا الْمَقْتُولُ وَقَالَ رَوْحٌ إِلَّا الْقَتِيلُ فِي سَبِيلِ اللهِ فَإِنَّهُ يُحِبُّ أَنْ يَرْجِعَ فَيُقْتَلَ مَرَّةً أُخْرَى
