Arabic (Original)
وَبِإِسْنَادِهِ عَنِ الْبَرَاءِ قَالَ قِيلَ هَذَا الَّذِينَ مَاتُوا قَبْلَ أَنْ تُحَوَّلَ إِلَى الْكَعْبَةِ وَرِجَالٌ قُتِلُوا فَلَمْ نَدْرِ مَا نَقُولُ فِيهِمْ فَأَنْزَلَ اللهُ ﷻ {وَمَا كَانَ اللهُ لِيُضِيعَ إِيمَانَكُمْ إِنَّ اللهَ بِالنَّاسِ لَرَءُوفٌ رَحِيمٌ} رَوَاهُمَا الْبُخَارِيُّ عَنْ أَبِي نُعَيْمٍ أَنْ تُحَوَّلَ إِلَى الْكَعْبَةِ وَرِجَالٌ قُتِلُوا فَلَمْ نَدْرِ مَا نَقُولُ فِيهِمْ فَأَنْزَلَ اللهُ ﷻ {وَمَا كَانَ اللهُ لِيُضِيعَ إِيمَانَكُمْ إِنَّ اللهَ بِالنَّاسِ لَرَءُوفٌ رَحِيمٌ} رَوَاهُمَا الْبُخَارِيُّ عَنْ أَبِي نُعَيْمٍ
English Translation
Through the same chain from al-Bara: "It was said about those who died before the qiblah was changed to the Ka'bah, and men who were killed — we did not know what to say about them. Then Allah revealed: 'And never would Allah have caused you to lose your faith. Indeed, Allah is, to the people, Kind and Merciful.'" [al-Baqarah 143] Recorded by al-Bukhari.
