[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, as you have not prayed." He mentioned this either twice or three times. The man said, "I do not know what you mean by not praying properly." The Messenger of Allah ﷺ said, "The prayer of none of you is complete until he performs ablution as Allah the Almighty has commanded. He washes his face and hands up to the elbows, wipes his head and feet up to the ankles. Then he says the takbeer, praises and glorifies Allah, recites from the Qur'an what Allah has permitted him, then he says the takbeer, bows and places his hands on his knees until his joints are still. Then he stands straight, saying, 'Allah hears whoever praises Him.' He stands straight until every bone returns to its place. Then he performs prostration and places his forehead on the ground until his joints are still. He stands straight, saying the takbeer, raises his head and sits straight on his sitting position while keeping his back straight. He establishes his prayer in this manner until he is finished. Then he said, 'None of your prayers are complete until you do this.'"
أَنَّهُ كَانَ جَالِسًا عِنْدَ رَسُولَ اللَّهِ ﷺ إِذْ جَاءَ رَجُلٌ فَدَخَلَ الْمَسْجِدَ فَصَلَّى فَلَمَّا قَضَى صَلَاتَهُ جَاءَ فَسَلَّمَ عَلَى رَسُولِ اللَّهِ ﷺ وَعَلَى الْقَوْمِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ «ارْجِعْ فَصَلِّ فَإِنَّكَ لَمْ تُصَلِّ» وَذَكَرَ ذَلِكَ إِمَّا مَرَّتَيْنِ أَوْ ثَلَاثَةً فَقَالَ الرَّجُلُ مَا أَدْرِي مَا عِبْتَ عَلَيَّ مِنْ صَلَاتِي فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّهَا لَا تَتِمُّ صَلَاةُ أَحَدٍ حَتَّى يُسْبِغَ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ ﷻ يَغْسِلُ وَجْهَهُ وَيَدَيْهِ إِلَى الْمِرْفَقَيْنِ وَيَمْسَحُ رَأْسَهُ وَرِجْلَهُ إِلَى الْكَعْبَيْنِ ثُمَّ يُكَبِّرُ وَيَحْمَدُ اللَّهَ وَيُمَجِّدُهُ وَيَقْرَأُ مِنَ الْقُرْآنِ مَا أَذِنَ اللَّهُ لَهُ فِيهِ ثُمَّ يُكَبِّرُ وَيَرْكَعُ وَيَضَعُ كَفَّيْهِ عَلَى رُكْبَتَيْهِ حَتَّى يَطْمَئِنَّ مَفَاصِلُهُ وَيَسْتَوِي ثُمَّ يَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ وَيَسْتَوِي قَائِمًا حَتَّى يَأْخُذَ كُلُّ عَظْمٍ مَأْخَذَهُ ثُمَّ يُقِيمُ صُلْبَهُ ثُمَّ يُكَبِّرُ فَيَسْجُدُ فَيُمَكِّنُ جَبْهَتَهُ مِنَ الْأَرْضِ حَتَّى يَطْمَئِنَّ مَفَاصِلُهُ وَيَسْتَوِي ثُمَّ يُكَبِّرُ فَيَرْفَعُ رَأْسَهُ وَيَسْتَوِي قَاعِدًا عَلَى مَقْعَدَتِهِ وَيُقِيمُ صُلْبَهُ فَوَصَفَ الصَّلَاةَ هَكَذَا حَتَّى فَرَغَ ثُمَّ قَالَ «لَا يَتِمُّ صَلَاةُ أَحَدِكُمْ حَتَّى يَفْعَلَ ذَلِكَ»
