Narrated Abu Huraira:
I went to Allah's Apostle while he was at Khaibar after it had fallen in the Muslims' hands. I said, "O Allah's Apostle! Give me a share (from the land of Khaibar)." One of the sons of Sa'id bin Al-'As said, "O Allah's Apostle! Do not give him a share." I said, "This is the murderer of Ibn Qauqal." The son of Said bin Al-As said, "Strange! A Wabr (i.e. guinea pig) who has come down to us from the mountain of Qaduim (i.e. grazing place of sheep) blames me for killing a Muslim who was given superiority by Allah because of me, and Allah did not disgrace me at his hands (i.e. was not killed as an infidel)." (The sub-narrator said "I do not know whether the Prophet gave him a share or not.")
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ
" يَضْحَكُ اللَّهُ إِلَى رَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا الآخَرَ يَدْخُلاَنِ الْجَنَّةَ، يُقَاتِلُ هَذَا فِي سَبِيلِ اللَّهِ فَيُقْتَلُ، ثُمَّ يَتُوبُ اللَّهُ عَلَى الْقَاتِلِ فَيُسْتَشْهَدُ ".
