Arabic hadith text
وَحَدَّثَنِي هَارُونُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا حَجَّاجُ بْنُ مُحَمَّدٍ، قَالَ قَالَ ابْنُ جُرَيْجٍ أَخْبَرَنِي صَالِحُ بْنُ كَيْسَانَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، - رضى الله عنهما - أَنَّهُ كَانَ يُخْبِرُ أَنَّ النَّبِيَّ صلى الله عليه وسلمأَهَلَّ حِينَ اسْتَوَتْ بِهِ نَاقَتُهُ قَائِمَةً .
