Sunan Ibn Majah 871
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 ـ صلى الله عليه وسلم ـ فَبَايَعْنَاهُ وَصَلَّيْنَا خَلْفَهُ فَلَمَحَ بِمُؤْخِرِ عَيْنِهِ رَجُلاً لاَ يُقِيمُ صَلاَتَهُ - يَعْنِي صُلْبَهُ - فِي الرُّكُوعِ وَالسُّجُودِ فَلَمَّا قَضَى النَّبِيُّ ـ صلى الله عليه وسلم ـ الصَّلاَةَ قَالَ " يَا مَعْشَرَ الْمُسْلِمِينَ لاَ صَلاَةَ لِمَنْ لاَ يُقِيمُ صُلْبَهُ فِي الرُّكُوعِ وَالسُّجُودِ " .
Ali ibn Shayban, who was among the delegation, said: We set out and came to the Messenger of Allah, pledged allegiance to him, and prayed behind him. He glanced from the corner of his eye at a man who was not straightening his prayer—that is, his back—during bowing and prostration. When the Prophet had finished the prayer, he said: O Muslims, there is no prayer for one who does not straighten his back during bowing and prostration.
