Sunan an-Nasa'i, Volume 4, Book 25, Hadith 3162 (DarusSalam) ⓘ

It was narrated that Anas said: "The Messenger of Allah said: 'A man from among the people of Paradise will be brought and Allah, the Mighty and Sublime, will say: "O son of Adam, how do you find your place (in Paradise)?" He would say: "O Lord, it is the best place." He will say: "Ask and wish (for whatever you want)." He would say: "I ask You to send me back to the world so that I may be killed in Your cause ten time" - because of what be sees of the virtue of martyrdom.'"

أَخْبَرَنَا أَبُو بَكْرِ بْنُ نَافِعٍ، قَالَ حَدَّثَنَا بَهْزٌ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ يُؤْتَى بِالرَّجُلِ مِنْ أَهْلِ الْجَنَّةِ فَيَقُولُ اللَّهُ عَزَّ وَجَلَّ يَا ابْنَ آدَمَ كَيْفَ وَجَدْتَ مَنْزِلَكَ فَيَقُولُ أَىْ رَبِّ خَيْرَ مَنْزِلٍ ‏.‏ فَيَقُولُ سَلْ وَتَمَنَّ فَيَقُولُ أَسْأَلُكَ أَنْ تَرُدَّنِي إِلَى الدُّنْيَا فَأُقْتَلَ فِي سَبِيلِكَ عَشْرَ مَرَّاتٍ لِمَا يَرَى مِنْ فَضْلِ الشَّهَادَةِ ‏" ‏ ‏.‏
