"Messenger of Allah entered the Masjid, and a man entered and offered Salat. Then he came to give Salam to the Propet. He returned the Salam to him and said: 'Go back and perform Salat, for indeed you have not prayed.' So the man returned to pray as he had prayed. Then he came to give Salam to the Prophet. He returned Salam to him, then [Messenger of Allah] said: 'Go back and perform Salat, for indeed you have not prayed' until he had done that three times. So the man said to him: 'By the One who sent you with the Truth, I do not know any better than this, so teach me.' So he said [to him]: 'When you stand for Salat then say the Takbir, then recite what is easy for you of the Quran. Then bow until you are at rest while bowing, then rise up until you are at rest sitting. Do that in all of your Salat.'"  

أَنَّ رَسُولَ اللَّهِ ﷺ دَخَلَ الْمَسْجِدَ فَدَخَلَ رَجُلٌ فَصَلَّى ثُمَّ جَاءَ فَسَلَّمَ عَلَى النَّبِيِّ ﷺ فَرَدَّ عَلَيْهِ السَّلاَمَ فَقَالَ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ فَرَجَعَ الرَّجُلُ فَصَلَّى كَمَا كَانَ صَلَّى ثُمَّ جَاءَ إِلَى النَّبِيِّ ﷺ فَسَلَّمَ عَلَيْهِ فَرَدَّ عَلَيْهِ السَّلاَمَ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ حَتَّى فَعَلَ ذَلِكَ ثَلاَثَ مِرَارٍ فَقَالَ لَهُ الرَّجُلُ وَالَّذِي بَعَثَكَ بِالْحَقِّ مَا أُحْسِنُ غَيْرَ هَذَا فَعَلِّمْنِي فَقَالَ إِذَا قُمْتَ إِلَى الصَّلاَةِ فَكَبِّرْ ثُمَّ اقْرَأْ بِمَا تَيَسَّرَ مَعَكَ مِنَ الْقُرْآنِ ثُمَّ ارْكَعْ حَتَّى تَطْمَئِنَّ رَاكِعًا ثُمَّ ارْفَعْ حَتَّى تَعْتَدِلَ قَائِمًا ثُمَّ اسْجُدْ حَتَّى تَطْمَئِنَّ سَاجِدًا ثُمَّ ارْفَعْ حَتَّى تَطْمَئِنَّ جَالِسًا وَافْعَلْ ذَلِكَ فِي صَلاَتِكَ كُلِّهَا  

"One day Messenger of Allah was sitting in the Masjid" Rifa'ah said: "And we were with him. Then what appeared to be a Bedouin man entered to pray, but he performed his Salat in a very brief manner. He then got up and greeted the prophet with Salam. The Prophet said (returning the greeting): 'And upon you. Go back and perform Salat, for indeed you have no prayed.' So he returned to perform Salat then came and greeted the Prophet with Salam. So he (the Prophet) said (returning the greeting): 'And upon you. Go back and perform Salat, for indeed you have not prayed.' [He did that] two or three times, each time coming to the Prophet, greeted the Prophet with Salam and the Prophet saying: 'And upon you. Go back and perform Salat, for indeed you have not prayed.' - until the people got scared and became very worried that one whose prayer was so brief had not actually prayed. Then in the end the man said: 'Then show me, and teach me, for I am a human who has suffered and is mistaken.' So he said: 'Alright. When you stand for Salat then perform Wudu as Allah ordered you. Then say the Tashahhud, and the Iqamah as well. If you know any Quran then recite it, if not then praise Allah, mention His greatness, and the Tahlil. Then bow such that you are at rest in your bowing, then stand completely, then prostrate completely, then sit such that you are at rest while sitting them stand. When you have done that, then you have completed your Salat, and if you leave out something, then you have made your Salat deficient.' And this was easier on them than the first matter, because if some of this was deficient, It would only reduce the reward of his Salat, it would not have gone entirely. "  

أَنَّ رَسُولَ اللَّهِ ﷺ بَيْنَمَا هُوَ جَالِسٌ فِي الْمَسْجِدِ يَوْمًا قَالَ رِفَاعَةُ وَنَحْنُ مَعَهُ إِذْ جَاءَهُ رَجُلٌ كَالْبَدَوِيِّ فَصَلَّى فَأَخَفَّ صَلاَتَهُ ثُمَّ انْصَرَفَ فَسَلَّمَ عَلَى النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ وَعَلَيْكَ فَارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ فَرَجَعَ فَصَلَّى ثُمَّ جَاءَ فَسَلَّمَ عَلَيْهِ فَقَالَ وَعَلَيْكَ فَارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ فَفَعَلَ ذَلِكَ مَرَّتَيْنِ أَوْ ثَلاَثًا كُلُّ ذَلِكَ يَأْتِي النَّبِيَّ ﷺ فَيُسَلِّمُ عَلَى النَّبِيِّ ﷺ فَيَقُولُ النَّبِيُّ ﷺ وَعَلَيْكَ فَارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ فَخَافَ النَّاسُ وَكَبُرَ عَلَيْهِمْ أَنْ يَكُونَ مَنْ أَخَفَّ صَلاَتَهُ لَمْ يُصَلِّ فَقَالَ الرَّجُلُ فِي آخِرِ ذَلِكَ فَأَرِنِي وَعَلِّمْنِي فَإِنَّمَا أَنَا بَشَرٌ أُصِيبُ وَأُخْطِئُ فَقَالَ أَجَلْ إِذَا قُمْتَ إِلَى الصَّلاَةِ فَتَوَضَّأْ كَمَا أَمَرَكَ اللَّهُ ثُمَّ تَشَهَّدْ وَأَقِمْ فَإِنْ كَانَ مَعَكَ قُرْآنٌ فَاقْرَأْ وَإِلاَّ فَاحْمَدِ اللَّهَ وَكَبِّرْهُ وَهَلِّلْهُ ثُمَّ ارْكَعْ فَاطْمَئِنَّ رَاكِعًا ثُمَّ اعْتَدِلْ قَائِمًا ثُمَّ اسْجُدْ فَاعْتَدِلْ سَاجِدًا ثُمَّ اجْلِسْ فَاطْمَئِنَّ جَالِسًا ثُمَّ قُمْ فَإِذَا فَعَلْتَ ذَلِكَ فَقَدْ تَمَّتْ صَلاَتُكَ وَإِنِ انْتَقَصْتَ مِنْهُ شَيْئًا انْتَقَصْتَ مِنْ صَلاَتِكَ قَالَ وَكَانَ هَذَا أَهْوَنَ عَلَيْهِمْ مِنَ الأَوَّلِ أَنَّهُ مَنِ انْتَقَصَ مِنْ ذَلِكَ شَيْئًا انْتَقَصَ مِنْ صَلاَتِهِ وَلَمْ تَذْهَبْ كُلُّهَا قَالَ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ وَعَمَّارِ بْنِ يَاسِرٍ  

[Machine] He was sitting with the Messenger of Allah ﷺ when a man came and entered the mosque and prayed. When he finished his prayer, he greeted the Messenger of Allah ﷺ and the people. The Messenger of Allah ﷺ said to him, "Go back and pray, for you have not prayed." He returned and prayed, and we observed his prayer, not knowing what was wrong with it. When he finished his prayer, he greeted the Messenger of Allah ﷺ and the people. The Messenger of Allah ﷺ said to him, "Go back and pray, for you have not prayed." He mentioned this either two or three times. The man said, "I do not know what wrong I have done in my prayer." The Messenger of Allah ﷺ said, "Indeed, the prayer is not complete for any of you until he performs ablution as prescribed by Allah. He should wash his face and hands up to the elbows, wipe his head and his feet up to the ankles, then he should say the takbir and praise and glorify Allah, and recite from the Qur'an whatever Allah has permitted him. Then he should say the takbir and bow, placing his palms on his knees until his joints are at rest, then he should stand up straight until all his bones return to their place, then he should say, 'Allah hears the one who praises Him.' Then he should stand until all his joints are at rest, then he should say the takbir and prostrate, placing his forehead on the ground until his joints are at rest, then he should stand up straight until all his bones return to their place, then he should say the takbir and sit on his left thigh, keeping his back straight, and then he should recite the tashahhud, and describe the prayer in this manner until he finishes. Then he said, 'The prayer of any one of you is not complete until he does that.'"  

أَنَّهُ كَانَ جَالِسًا عِنْدَ رَسُولِ اللهِ ﷺ إِذْ جَاءَ رَجُلٌ فَدَخَلَ الْمَسْجِدَ فَصَلَّى فَلَمَّا قَضَى صَلَاتَهُ جَاءَ فَسَلَّمَ عَلَى رَسُولِ اللهِ ﷺ وَعَلَى الْقَوْمِ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ وَعَلَيْكَ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ قَالَ فَرَجَعَ فَصَلَّى فَجَعَلْنَا نَرْمُقُ صَلَاتَهُ لَا نَدْرِي مَا يَعِيبُ مِنْهَا فَلَمَّا قَضَى صَلَاتَهُ جَاءَ فَسَلَّمَ عَلَى رَسُولِ اللهِ ﷺ وَعَلَى الْقَوْمِ فَقَالَ رَسُولُ اللهِ ﷺ ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ وَذَكَرَ ذَلِكَ إِمَّا مَرَّتَيْنِ أَوْ إِمَّا ثَلَاثًا فَقَالَ الرَّجُلُ مَا أَدْرِي مَا عِبْتَ عَلَيَّ مِنْ صَلَاتِي فَقَالَ رَسُولُ اللهِ ﷺ إِنَّهَا لَا تَتِمُّ صَلَاةُ أَحَدِكُمْ حَتَّى يُسْبِغَ الْوُضُوءَ كَمَا أَمَرَهُ اللهُ تَعَالَى يَغْسِلُ وَجْهَهُ وَيَدَيْهِ إِلَى الْمِرْفَقَيْنِ وَيَمْسَحُ بِرَأْسِهِ وَرِجْلَيْهِ إِلَى الْكَعْبَيْنِ ثُمَّ يُكَبِّرُ وَيَحْمَدُ اللهَ وَيُمَجِّدُهُ وَيَقْرَأُ مِنَ الْقُرْآنِ مَا أَذِنَ اللهُ لَهُ فِيهِ ثُمَّ يُكَبِّرُ فَيَرْكَعُ وَيَضَعُ كَفَّيْهِ عَلَى رُكْبَتَيْهِ حَتَّى تَطْمَئِنَّ مَفَاصِلُهُ فَيَسْتَوِيَ ثُمَّ يَقُولُ سَمِعَ اللهُ لِمَنْ حَمِدَهُ وَيَسْتَوِي قَائِمًا حَتَّى يَأْخُذَ كُلُّ عُضْوٍ مَأْخَذَهُ ثُمَّ يُقِيمُ صُلْبَهُ ثُمَّ يُكَبِّرُ فَيَسْجُدُ فَيُمَكِّنُ جَبْهَتَهُ مِنَ الْأَرْضِ حَتَّى تَطْمَئِنَّ مَفَاصِلُهُ وَيَسْتَوِيَ ثُمَّ يُكَبِّرُ فَيَرْفَعُ رَأْسَهُ وَيَسْتَوِي قَاعِدًا عَلَى مَقْعَدَتِهِ وَيُقِيمُ صُلْبَهُ فَوَصَفَ الصَّلَاةَ هَكَذَا حَتَّى فَرَغَ ثُمَّ قَالَ لَا تَتِمُّ صَلَاةُ أَحَدِكُمْ حَتَّى يَفْعَلَ ذَلِكَ  

When the Messenger of Allah ﷺ entered the mosque, a man also entered it and prayed. He then came and saluted the Messenger of Allah ﷺ. The Messenger of Allah ﷺ returned the salutation and said to him: Go back and pray, for you have not prayed. The man returned and prayed as he prayed before. He then came to prophet ﷺ and saluted him. The Messenger of Allah ﷺ said to him: “ And upon you be peace. “ Go back and pray, for you have not prayed. He did so three times. Then the man said: By Him who has sent you(as a Prophet) with truth; I cannot do better than this; so teach me. He said: When you get up to pray, utter the takbir(Allah is most great); then recite a convenient portion of the Qur’an; then bow and remain quietly in that position; then sit and remain quietly in that position; then raise yourself and stand erect: then prostrate yourself and remain quietly in that position; then sit and remain quietly in that position; then do that throughout all your prayer. Abu Dawud said: Al-Qa’nabi reported this tradition from Sa’id b. Abi Sa’Id on the authority of Abu Hurairah. This version has the wording in the last: When you do this, then your prayer is completed. If you omit anything form this, you omit that much from your prayer. This version also has the wording: when you get up for praying, perform the abulation perfectly. (Using translation from Abū Dāʾūd 856)
