I heard him narrate, saying that whenever the Prophet ﷺ rose after the two prostrations, he would say the takbir and raise his hands until they were level with his shoulders, just as he did when he began the prayer.
أخبرنا يعقوب بن إبراهيم الدورقي ومحمد بن بشار واللفظ له قالا حدثنا يحيى بن سعيد قال حدثنا عبد الحميد بن جعفر قال حدثني محمد بن عمرو بن عطاء
سمعته يحدث قال كان النبي ﷺ إذا قام من السجدتين كبر ورفع يديه حتى يحاذي بهما منكبيه كما صنع حين افتتح الصلاة
