Arabic hadith text
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، حَدَّثَنَا مُوسَى بْنُ عُبَيْدَةَ، حَدَّثَنِي سَعِيدُ بْنُ أَبِي سَعِيدٍ، عَنِ الأَدْرَعِ السُّلَمِيِّ، قَالَ جِئْتُ لَيْلَةً أَحْرُسُ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَإِذَا رَجُلٌ قِرَاءَتُهُ عَالِيَةٌ فَخَرَجَ النَّبِيُّ ـ صلى الله عليه وسلم ـ فَقُلْتُ يَا رَسُولَ اللَّهِ هَذَا مُرَاءٍ ‏.‏ قَالَ فَمَاتَ بِالْمَدِينَةِ فَفَرَغُوا مِنْ جِهَازِهِ فَحَمَلُوا نَعْشَهُ فَقَالَ النَّبِيُّ ـ صلى الله عليه وسلم ـ ‏"‏ ارْفُقُوا بِهِ رَفَقَ اللَّهُ بِهِ إِنَّهُ كَانَ يُحِبُّ اللَّهَ وَرَسُولَهُ ‏"‏ ‏.‏ قَالَ وَحَفَرَ حُفْرَتَهُ فَقَالَ ‏"‏ أَوْسِعُوا لَهُ وَسَّعَ اللَّهُ عَلَيْهِ ‏"‏ ‏.‏ فَقَالَ بَعْضُ أَصْحَابِهِ يَا رَسُولَ اللَّهِ لَقَدْ حَزِنْتَ عَلَيْهِ ‏.‏ فَقَالَ ‏"‏ أَجَلْ إِنَّهُ كَانَ يُحِبُّ اللَّهَ وَرَسُولَهُ ‏"
