Arabic (Original)
قَالَ حَدَّثَنَا أَبُو النَّضْرِ قَالَ حَدَّثَنَا أَيُّوبُ بْنُ عُتْبَةَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ بَدْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَلِيِّ بْنِ شَيْبَانَ عَنْ أَبِيهِ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَا يَنْظُرُ اللَّهُ عَزَّ وَجَلَّ إِلَى رَجُلٍ لَا يُقِيمُ صُلْبَهُ بَيْنَ رُكُوعِهِ وَسُجُودِهِ.

He said: Abu al-Nadr told us: Ayyub ibn 'Utbah told us: 'Abd Allah ibn Badr told us, from 'Abd al-Rahman ibn 'Ali ibn Shayban, from his father, that the Messenger of Allah, peace and blessings be upon him, said: Allah, mighty and majestic, does not look upon a man who does not straighten his back between his bowing and his prostration.
