The bowing in Prayer

It was narrated that ‘Aishah said:
“When the Messenger of Allah ﷺ bowed, he neither raised his head nor lowered it, rather (he did something) between that.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ بُدَيْلٍ، عَنْ أَبِي الْجَوْزَاءِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا رَكَعَ لَمْ يَشْخَصْ رَأْسَهُ وَلَمْ يُصَوِّبْهُ وَلَكِنْ بَيْنَ ذَلِكَ .

It was narrated that Abu Mas’ud said:
“The Messenger of Allah ﷺ said: ‘No prayer is acceptable in which a man does not settle his spine when bowing and when prostrating.’”

حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَعَمْرُو بْنُ عَبْدِ اللَّهِ، قَالاَ حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ عُمَارَةَ، عَنْ أَبِي مَعْمَرٍ، عَنْ أَبِي مَسْعُودٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " لاَ تُجْزِئُ صَلاَةٌ لاَ يُقِيمُ الرَّجُلُ فِيهَا صُلْبَهُ فِي الرُّكُوعِ وَالسُّجُودِ " .

It was narrated that ‘Ali bin Shaiban who was part of a delegation (to the Prophet ﷺ) said:
“We set out until we came to the Messenger of Allah ﷺ, and we gave him our oath of allegiance and performed prayer behind him. He glanced out of the corner of his eye at a man who was not settling his spine when he bowed and prostrated. When the Prophet ﷺ finished the prayer, he said: ‘O Muslims, there is no prayer for the one who does not settle his spine when bowing and prostrating.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُلاَزِمُ بْنُ عَمْرٍو، عَنْ عَبْدِ اللَّهِ بْنِ بَدْرٍ، أَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ عَلِيِّ بْنِ شَيْبَانَ، عَنْ أَبِيهِ، . عَلِيِّ بْنِ شَيْبَانَ - وَكَانَ مِنَ الْوَفْدِ - قَالَ خَرَجْنَا حَتَّى قَدِمْنَا عَلَى رَسُولِ اللَّهِ ﷺ فَبَايَعْنَاهُ وَصَلَّيْنَا خَلْفَهُ فَلَمَحَ بِمُؤْخِرِ عَيْنِهِ رَجُلاً لاَ يُقِيمُ صَلاَتَهُ - يَعْنِي صُلْبَهُ - فِي الرُّكُوعِ وَالسُّجُودِ فَلَمَّا قَضَى النَّبِيُّ ﷺ الصَّلاَةَ قَالَ " يَا مَعْشَرَ الْمُسْلِمِينَ لاَ صَلاَةَ لِمَنْ لاَ يُقِيمُ صُلْبَهُ فِي الرُّكُوعِ وَالسُّجُودِ " .
