Jami` at-Tirmidhi 2402
Jabir narrated that the Prophet (s.a.w) said:
"On the Day of Judgement, when the people who were tried (in this world) are given their rewards, the people who were pardoned (in life), will wish that their skins had been cut off with scissors while they were in the world."

This Hadith is Gharib, we do not know of it with this chain except through this route. Some of them have reported something similar to this Hadith from Al-A`mash, from Talhah bin Musarrif from Masruq.
حَدَّثَنَا مُحَمَّدُ بْنُ حُمَيْدٍ الرَّازِيُّ، وَيُوسُفُ بْنُ مُوسَى الْقَطَّانُ الْبَغْدَادِيُّ، قَالاَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَغْرَاءَ أَبُو زُهَيْرٍ، عَنِ الأَعْمَشِ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ يَوَدُّ أَهْلُ الْعَافِيَةِ يَوْمَ الْقِيَامَةِ حِينَ يُعْطَى أَهْلُ الْبَلاَءِ الثَّوَابَ لَوْ أَنَّ جُلُودَهُمْ كَانَتْ قُرِضَتْ فِي الدُّنْيَا بِالْمَقَارِيضِ ‏"‏ ‏.‏ وَهَذَا حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ بِهَذَا الإِسْنَادِ إِلاَّ مِنْ هَذَا الْوَجْهِ ‏.‏ وَقَدْ رَوَى بَعْضُهُمْ هَذَا الْحَدِيثَ عَنِ الأَعْمَشِ عَنْ طَلْحَةَ بْنِ مُصَرِّفٍ عَنْ مَسْرُوقٍ قَوْلَهُ شَيْئًا مِنْ هَذَا ‏.‏
