It was narrated that ‘Aishah said:“When the Messenger of Allah (ﷺ) raised his head from bowing, he would not prostrate until he had stood up straight. When he prostrated, he would raise his head and not prostrate again until he had sat up straight. And he used to spread out his left leg.”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ بُدَيْلٍ، عَنْ أَبِي الْجَوْزَاءِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ لَمْ يَسْجُدْ حَتَّى يَسْتَوِيَ قَائِمًا، فَإِذَا سَجَدَ فَرَفَعَ رَأْسَهُ، لَمْ يَسْجُدْ حَتَّى يَسْتَوِيَ جَالِسًا، وَكَانَ يَفْتَرِشُ رِجْلَهُ الْيُسْرَى .
