Musannaf 'Abd al-Razzaq 3511
✧ Standing up where one should sit
3511 3484 - عَبْدُ الرَّزَّاقِ، عَنِ الثَّوْرِيِّ عَنْ..... قَالَ: إِذَا قَامَ الرَّجُلُ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ فَلْيُسَبِّحْ بِهِ، فَإِنْ كَانَ قَدِ اسْتَتَمَّ قَائِمًا فَلَا يَجْلِسْ، وَإِنْ كَانَ لَمْ يَسْتَتِمَّ قَائِمًا فَلْيَجْلِسْ ".
Translation
✧ If a man stands up in the first two rakʿahs, they should say subḥān Allāh to him. If he has become fully upright, he should not sit; but if he has not yet become fully upright, he should sit.
