Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَضْحَكُ اللَّهُ لِرَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا الْآخَرَ كِلَاهُمَا يَدْخُلُ الْجَنَّةَ قَالُوا كَيْفَ يَا رَسُولَ اللَّهِ قَالَ يَقْتُلُ هَذَا فَيَلِجُ الْجَنَّةَ ثُمَّ يَتُوبُ اللَّهُ عَلَى الْآخَرِ فَيَهْدِيهِ إِلَى الْإِسْلَامِ ثُمَّ يُجَاهِدُ فِي سَبِيلِ اللَّهِ فَيُسْتَشْهَدُ.
English Translation
The Messenger of Allah (peace be upon him) said: 'Allah rejoices at two men: one kills the other, yet both enter Paradise.' They asked: 'How is that, O Messenger of Allah?' He said: 'One is killed and enters Paradise. Then Allah accepts the repentance of the other and guides him to Islam. He then fights in the cause of Allah and is martyred.'
