حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ وَعَمْرُو بْنُ عَبْدِ اللَّهِ قَالَا حَدَّثَنَا وَکِيعٌ عَنْ الْأَعْمَشِ عَنْ عُمَارَةَ عَنْ أَبِي مَعْمَرٍ عَنْ أَبِي مَسْعُودٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ لَا تُجْزِئُ صَلَاةٌ لَا يُقِيمُ الرَّجُلُ فِيهَا صُلْبَهُ فِي الرُّکُوعِ وَالسُّجُودِ
ابن ماجہ · Hadith 870
It was narrated that' Aishah said: "When the Messenger of Allah P.B.U.H bowed, he neither raised his head nor lowered it, rather (he did something) between that."(Sahih)
