Jami` at-Tirmidhi, Hadith 1661 ⓘ
Narrated Anas bin Malik: That the Messenger of Allah said: "None of the people of Paradise would wish to return to the world except for the martyr who indeed would love to return to the world saying that he would love to be killed ten times in Allah's cause because of what he has seen of the honor that He has given him." [Abu 'Eisa said:] This Hadith is Hasan Sahih.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُعَاذُ بْنُ هِشَامٍ، حَدَّثَنِي أَبِي، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَا مِنْ أَحَدٍ مِنْ أَهْلِ الْجَنَّةِ يَسُرُّهُ أَنْ يَرْجِعَ إِلَى الدُّنْيَا غَيْرُ الشَّهِيدِ فَإِنَّهُ يُحِبُّ أَنْ يَرْجِعَ إِلَى الدُّنْيَا يَقُولُ حَتَّى أُقْتَلَ عَشْرَ مَرَّاتٍ فِي سَبِيلِ اللَّهِ مِمَّا يَرَى مِمَّا أَعْطَاهُ اللَّهُ مِنَ الْكَرَامَةِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ صَحِيحٌ .
