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)   

أَنَّ النَّبِيَّ ﷺ دَخَلَ الْمَسْجِدَ فَدَخَلَ رَجُلٌ فَصَلَّى ثُمَّ جَاءَ فَسَلَّمَ عَلَى النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ وَعَلَيْكَ السَّلَامُ ارْجِعْ فَصَلِّي فَإِنَّكَ لَمْ تُصَلِّ حَتَّى فَعَلَ ذَلِكَ ثَلَاثَ مَرَّاتٍ فَقَالَ الرَّجُلُ وَالَّذِي بَعَثَكَ بِالْحَقِّ مَا أُحْسِنُ غَيْرَ هَذَا فَأَرِنِي وَعَلِّمْنِي قَالَ إِذَا قُمْتَ إِلَى الصَّلَاةِ فَكَبِّرْ ثُمَّ اقْرَأْ مَا تَيَسَّرَ مَعَكَ مِنَ الْقُرْآنِ ثُمَّ ارْكَعْ حَتَّى تَطْمَئِنَّ رَاكِعًا ثُمَّ ارْفَعْ حَتَّى تَعْتَدِلَ قَائِمًا ثُمَّ اسْجُدْ حَتَّى تَطْمَئِنَّ سَاجِدًا ثُمَّ ارْفَعْ حَتَّى تَطْمَئِنَّ جَالِسًا ثُمَّ افْعَلْ ذَلِكَ فِي صَلَاتِكَ كُلِّهَا أَخْرَجَاهُ مِنْ حَدِيثِ يَحْيَى الْقَطَّانِ  

عَنِ النَّبِيِّ ﷺ وَقَالَ فِي آخِرِهِ ثُمَّ كَذَلِكَ فِي كُلِّ رَكْعَةٍ وَسَجْدَةٍ أَخْبَرَنَاهُ مُحَمَّدُ بْنُ عَبْدِ اللهِ الْحَافِظُ أنبأ أَبُو نَصْرٍ الْخَفَّافُ ثنا أَحْمَدُ بْنُ سَلَمَةَ ثنا إِسْحَاقُ بْنُ إِبْرَاهِيمَ فَذَكَرَهُ  

[Machine] Abu Hurairah said, "If you are an imam, then shorten the prayer, for among the people there are elderly, weak, and those in need. But if you pray alone, then prolong what appears good to you. In every prayer, recite aloud, for what the Messenger of Allah ﷺ heard, we also hear, and what he whispered, we also whispered. Then, a man asked him, 'What do you think if I do not exceed the Umm al-Quran?' He said, 'If you exceed it, it is good, and if you reach it, it suffices you.'"  

قَالَ أَبُو هُرَيْرَةَ ؓ إِذَا كُنْتَ إِمَامًا فَخَفِّفْ فَإِنَّ فِي النَّاسِ الْكَبِيرَ وَالضَّعِيفَ وَذَا الْحَاجَةِ وَإِذَا صَلَّيْتَ وَحْدَكَ فَطَوِّلْ مَا بَدَا لَكَ وَفِي كُلِّ صَلَاةٍ اقْرَأْ فَمَا أَسْمَعَنَا رَسُولُ اللهِ ﷺ أَسْمَعْنَاكُمْ وَمَا أَخْفَى عَنَّا أَخْفَيْنَا عَنْكُمْ فَقَالَ لَهُ رَجُلٌ أَرَأَيْتَ إِنْ لَمْ أَزِدْ عَلَى أُمِّ الْقُرْآنِ؟ قَالَ إِنْ زِدْتَ عَلَيْهَا فَهُوَ خَيْرٌ وَإِنِ انْتَهَيْتَ إِلَيْهَا أَجْزَأَ عَنْكَ
