Arabic (Original)
حَدَّثَنَا عَفَّانُ وَبَهْزٌ قَالَا حَدَّثَنَا شُعْبَةُ قَالَ سَعْدُ بْنُ إِبْرَاهِيمَ أَخْبَرَنِي قَالَ سَمِعْتُ أَبَا عُبَيْدَةَ يُحَدِّثُ عَنْ أَبِيهِ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ فِي الرَّكْعَتَيْنِ الْأُوَلَتَيْنِ كَأَنَّهُ عَلَى الرَّضْفِ قُلْتُ حَتَّى يَقُومَ قَالَ حَتَّى يَقُومَ.
