Sahih al-Bukhari 5785

Arabic

حَدَّثَنِي مُحَمَّدٌ، أَخْبَرَنَا عَبْدُ الأَعْلَى، عَنْ يُونُسَ، عَنِ الْحَسَنِ، عَنْ أَبِي بَكْرَةَ ـ رضى الله عنه ـ قَالَ خَسَفَتِ الشَّمْسُ وَنَحْنُ عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَقَامَ يَجُرُّ ثَوْبَهُ مُسْتَعْجِلاً، حَتَّى أَتَى الْمَسْجِدَ وَثَابَ النَّاسُ فَصَلَّى رَكْعَتَيْنِ، فَجُلِّيَ عَنْهَا، ثُمَّ أَقْبَلَ عَلَيْنَا وَقَالَ ‏ "‏ إِنَّ الشَّمْسَ وَالْقَمَرَ آيَتَانِ مِنْ آيَاتِ اللَّهِ، فَإِذَا رَأَيْتُمْ مِنْهَا شَيْئًا فَصَلُّوا وَادْعُوا اللَّهَ حَتَّى يَكْشِفَهَا ‏"‏‏.‏
