Sahih Bukhari
كتاب الأذان (صفة الصلوة)
The Book of Adhan (Sufa-tus-Salat)
بَابُ إِذَا لَمْ يُتِمَّ السُّجُودَ:
(132) Chapter. If one does not perform the prostrations perfectly.
Hadith 808
حَدَّثَنَا الصَّلْتُ بْنُ مُحَمَّدٍ ، قَالَ : حَدَّثَنَا مَهْدِيُّ ، عَنْ وَاصِلٍ ، عَنْ أَبِي وَائِلٍ ، عَنْ حُذَيْفَةَ " رَأَى رَجُلًا لَا يُتِمُّ رُكُوعَهُ وَلَا سُجُودَهُ فَلَمَّا قَضَى صَلَاتَهُ ، قَالَ لَهُ حُذَيْفَةُ : مَا صَلَّيْتَ ، قَالَ : وَأَحْسِبُهُ ، قَالَ : وَلَوْ مُتَّ مُتَّ عَلَى غَيْرِ سُنَّةِ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " .
Narrated Abu Wail: Hudhaifa said, "I saw a person not performing his bowing and prostrations perfectly. When he completed the prayer, I told him that he had not prayed." I think that Hudhaifa added (i.e. said to the man), "Had you died, you would have died on a tradition other than that of the Prophet Muhammad."
