[Machine] The Messenger of Allah ﷺ said to us, "Pray as you have seen me praying. When the prayer time comes, let one of you give the call to prayer and the one among you who knows the most should lead the prayer."  

قَالَ لَنَا رَسُولُ اللهِ ﷺ صَلُّوا كَمَا رَأَيْتُمُونِي أُصَلِّي فَإِذَا حَضَرَتِ الصَّلَاةُ فَلْيُؤَذِّنْ لَكُمْ أَحَدُكُمْ وَلْيَؤُمَّكُمْ أَكْبَرُكُمْ  

[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
