[Machine] A man entered the mosque and the Messenger of Allah ﷺ was sitting, so he prayed. The Messenger of Allah ﷺ commanded him to repeat his prayer two or three times. The man asked, "O Messenger of Allah, why do I have to repeat my prayer two or three times?" The Messenger of Allah ﷺ said, "The prayer of none of the people is complete until he performs ablution, placing the ablution in its proper places, then he says 'Allahu Akbar' (Allah is the Greatest), then praises Allah the Almighty and glorifies Him, then recites whatever is easy for him from the Qur'an, then he says 'Allahu Akbar' (Allah is the Greatest) until he feels relaxation in his joints, then he says 'Samia Allahu liman hamidah' (Allah hears whoever praises Him), until he is standing straight, then he says 'Allahu Akbar' (Allah is the Greatest) and prostrates until he feels relaxation in his joints, then he raises his head until he is sitting straight, then he prostrates again until he feels relaxation in his joints. If he does not do this, his prayer is not complete."
أَنَّ رَجُلًا دَخَلَ الْمَسْجِدَ وَرَسُولُ اللهِ ﷺ جَالِسٌ فَصَلَّى فَأَمَرَهُ رَسُولُ اللهِ ﷺ فَأَعَادَ مَرَّتَيْنِ أَوْ ثَلَاثًا فَقَالَ يَا رَسُولَ اللهِ مَا أَلَوْتُ بَعْدَ مَرَّتَيْنِ أَوْ ثَلَاثٍ أَنْ أُتِمَّ صَلَاتِي فَقَالَ رَسُولُ اللهِ ﷺ إِنَّهُ لَا تَتِمُّ صَلَاةٌ لِأَحَدٍ مِنَ النَّاسِ حَتَّى يَتَوَضَّأَ فَيَضَعَ الْوُضُوءَ مَوَاضِعَهُ ثُمَّ يَقُولُ اللهُ أَكْبَرُ ثُمَّ يَحْمَدُ اللهَ تَعَالَى وَيُثْنِي عَلَيْهِ وَيَقْرَأُ مَا تَيَسَّرَ مِنَ الْقُرْآنِ ثُمَّ يُكَبِّرُ حَتَّى تَطْمَئِنَّ مَفَاصِلُهُ ثُمَّ يَقُولُ سَمِعَ اللهُ لِمَنْ حَمِدَهُ حَتَّى يَسْتَوِيَ قَائِمًا ثُمَّ يُكَبِّرُ وَيَسْجُدُ حَتَّى تَطْمَئِنَّ مَفَاصِلُهُ ثُمَّ يَرْفَعُ رَأْسَهُ حَتَّى يَسْتَوِيَ قَاعِدًا ثُمُّ يَسْجُدُ حَتَّى تَطْمَئِنَّ مَفَاصِلُهُ فَإِذَا لَمْ يَفْعَلْ ذَلِكَ لَمْ تَتِمَّ صَلَاتُهُ
