صحيح البخاري Sahih Bukhari كتاب الجهاد والسير The Book of Jihad (Fighting For Allah’S Cause)
بَابُ فَضْلِ قَوْلِ اللَّهِ تَعَالَى: {وَلاَ تَحْسِبَنَّ الَّذِينَ قُتِلُوا فِي سَبِيلِ اللَّهِ أَمْوَاتًا بَلْ أَحْيَاءٌ عِنْدَ رَبِّهِمْ يُرْزَقُونَ فَرِحِينَ بِمَا آتَاهُمُ اللَّهُ مِنْ فَضْلِهِ وَيَسْتَبْشِرُونَ بِالَّذِينَ لَمْ يَلْحَقُوا بِهِمْ مِنْ خَلْفِهِمْ أَنْ لاَ خَوْفٌ عَلَيْهِمْ وَلاَ هُمْ يَحْزَنُونَ يَسْتَبْشِرُونَ بِنِعْمَةٍ مِنَ اللَّهِ وَفَضْلٍ وَأَنَّ اللَّهَ لاَ يُضِيعُ أَجْرَ الْمُؤْمِنِينَ} :

(19) Chapter. The superiority of (those people for whom) the following Statement of Allah (was revealed): “Think not of those who are killed in the Way of Allah as dead. Nay, they are alive, with their Lord, and they have provision. They rejoice in what Allah has betowed upon them of His Bounty, and rejoice for the sake of those who have not yet joined them, but are left behind (not yet martyred) that on them no fear shall come, nor shall they grieve. They rejoice in aGrace and a Bounty from Allah, and that Allah will not waste the reward of the believers." (V.3:169-171)

حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَبْدِ اللَّهِ ، قَالَ : حَدَّثَنِي مَالِكٌ ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ ، عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ ، قَالَ : "دَعَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَلَى الَّذِينَ قَتَلُوا أَصْحَابَ بِئْرِ مَعُونَةَ ثَلَاثِينَ غَدَاةً عَلَى رِعْلٍ ، وَذَكْوَانَ وَعُصَيَّةَ عَصَتِ اللَّهَ وَرَسُولَهُ ، قَالَ أَنَسٌ : أُنْزِلَ فِي الَّذِينَ قُتِلُوا بِبِئْرِ مَعُونَةَ قُرْآنٌ قَرَأْنَاهُ ، ثُمَّ نُسِخَ بَعْدُ بَلِّغُوا قَوْمَنَا أَنْ قَدْ لَقِينَا رَبَّنَا فَرَضِيَ عَنَّا وَرَضِينَا عَنْهُ " .
Narrated Anas bin Malik: For thirty days Allah's Apostle invoked Allah to curse those who had killed the companions of Bir- Mauna; he invoked evil upon the tribes of Ral, Dhakwan, and Usaiya who disobeyed Allah and His Apostle. There was reveled about those who were killed at Bir-Mauna a Qur'anic Verse we used to recite, but it was cancelled later on. The Verse was: "Inform our people that we have met our Lord. He is pleased with us and He has made us pleased."
