Unreviewed translation. All hadiths in this collection are available in five languages. Titles and introductions may remain in Arabic.
Ahmad ibn Mani narrated to us: Abu Muawiyah narrated to us, from al-A‘mash, from Umarah ibn Umayr, from Abu Ma‘mar, from Abu Masud al-Ansari al-Badri, who said: The Messenger of Allah said: ‘A prayer does not suffice if a man does not straighten his back in bowing and prostration.’
Reports on this subject are also related from Ali ibn Shayban, Anas, Abu Hurayrah, and Rifa‘ah al-Zuraqi. Abu Isa said: The hadith of Abu Masud al-Ansari is hasan sahih. The Prophet’s Companions and those after them acted on this: they held that a man must straighten his back in bowing and prostration. Al-Shafi‘i, Ahmad, and Ishaq said that if a man does not straighten his back in bowing and prostration, his prayer is invalid, based on the Prophet’s statement: ‘A prayer does not suffice if a man does not straighten his back in bowing and prostration.’ Abu Ma‘mar’s name was Abd Allah ibn Sakhbarah. Abu Masud al-Ansari al-Badri’s name was Uqbah ibn Amr.
Notes and open questions — unreviewed
The commentary attributes the invalidity ruling specifically to al-Shafi‘i, Ahmad, and Ishaq, and identifies straightening the back as a requirement in bowing and prostration.
وَقَالَ الشَّافِعِيُّ وَأَحْمَدُ وَإِسْحَاقُ مَنْ لَمْ يُقِمْ صُلْبَهُ فِي الرُّكُوعِ وَالسُّجُودِ فَصَلاَتُهُ فَاسِدَةٌ لِحَدِيثِ النَّبِيِّ صلى الله عليه وسلم " لاَ تُجْزِئُ صَلاَةٌ لاَ يُقِيمُ الرَّجُلُ فِيهَا صُلْبَهُ فِي الرُّكُوعِ وَالسُّجُودِ " .
The source reports a specific invalidity ruling from three named jurists, grounded in the phrase that the prayer does not suffice.
Is this ruling kept explicitly attributed to the named jurists?
