“The Prophet ﷺ said to me: ‘When you raise your head from prostration, do not squat like a dog. Put your buttocks between your feet and let the tops of your feet touch the ground.”  

ابن ماجة:٨٩٦حَدَّثَنَا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ الصَّبَّاحِ حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَنْبَأَنَا الْعَلاَءُ أَبُو مُحَمَّدٍ قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ قَالَ

لِي النَّبِيُّ ﷺ إِذَا رَفَعْتَ رَأْسَكَ مِنَ السُّجُودِ فَلاَ تُقْعِ كَمَا يُقْعِي الْكَلْبُ ضَعْ أَلْيَتَيْكَ بَيْنَ قَدَمَيْكَ وَأَلْزِقْ ظَاهِرَ قَدَمَيْكَ بِالأَرْضِ

“The Prophet ﷺ said to me: ‘When you raise your head from prostration, do not squat like a dog. Put your buttocks between your feet and let the tops of your feet touch the ground.” (Using translation from Ibn Mājah 896)   

السيوطي:١٨٩٦a

"إِذَا رفعْتَ رأسَك منَ السُّجودِ فلا تُقْع كما يُقْعِى الكلبُ ضَعْ ألْيَيكَ بَينَ قَدَمَيكَ والْزقْ (ظَاهرَ) قَدَمَيكَ بالأرْضِ".
