It was narrated to me that the Messenger of Allah ﷺ had said: The prayer observed by a person sitting is half of the prayer. I came to him ﷺ and found him praying in a sitting position. I placed my hand on his head. He said: O 'Abdullah b. 'Amr, what is the matter with you? I said: Messenger of Allah, it has been narrated to me that you said: The prayer of a man in a sitting position is half of the prayer, whereas you are observing prayer sitting. He (the Holy Prophet) said: Yes, it is so, but I am not like anyone amongst you.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ صَلاَةُ الرَّجُلِ قَاعِدًا نِصْفُ الصَّلاَةِ قَالَ فَأَتَيْتُهُ فَوَجَدْتُهُ يُصَلِّي جَالِسًا فَوَضَعْتُ يَدِي عَلَى رَأْسِهِ فَقَالَ مَا لَكَ يَا عَبْدَ اللَّهِ بْنَ عَمْرٍو قُلْتُ حُدِّثْتُ يَا رَسُولَ اللَّهِ أَنَّكَ قُلْتَ صَلاَةُ الرَّجُلِ قَاعِدًا عَلَى نِصْفِ الصَّلاَةِ وَأَنْتَ تُصَلِّي قَاعِدًا قَالَ أَجَلْ وَلَكِنِّي لَسْتُ كَأَحَدٍ مِنْكُمْ  

"I saw the Prophet ﷺ praying sitting down and I said: 'I was told that you said that the prayer of one who is sitting down is worth half of the prayer of the one who is standing up.' He said: 'Yes indeed, but I am not like any one of you.'"  

رَأَيْتُ النَّبِيَّ ﷺ يُصَلِّي جَالِسًا فَقُلْتُ حُدِّثْتُ أَنَّكَ قُلْتَ إِنَّ صَلاَةَ الْقَاعِدِ عَلَى النِّصْفِ مِنْ صَلاَةِ الْقَائِمِ وَأَنْتَ تُصَلِّي قَاعِدًا قَالَ أَجَلْ وَلَكِنِّي لَسْتُ كَأَحَدٍ مِنْكُمْ  

It has been narrated to me that the Messenger of Allah ﷺ said : The Prayer of a man in sitting condition is half the prayer (wins him half the reward of prayer). I came to him and found him prayer in sitting condition. I placed my hand on my head (in surprise). He said: what is the matter,’Abd Allah b. ‘Amr? I said; Messenger of Allah ﷺ you have been reported to me as saying : the prayer of a man in sitting condition is half the prayer , but you are praying in sitting condition. He said: yes, but I am not like one of you.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ صَلاَةُ الرَّجُلِ قَاعِدًا نِصْفُ الصَّلاَةِ فَأَتَيْتُهُ فَوَجَدْتُهُ يُصَلِّي جَالِسًا فَوَضَعْتُ يَدَىَّ عَلَى رَأْسِي فَقَالَ مَا لَكَ يَا عَبْدَ اللَّهِ بْنَ عَمْرٍو قُلْتُ حُدِّثْتُ يَا رَسُولَ اللَّهِ أَنَّكَ قُلْتَ صَلاَةُ الرَّجُلِ قَاعِدًا نِصْفُ الصَّلاَةِ وَأَنْتَ تُصَلِّي قَاعِدًا قَالَ أَجَلْ وَلَكِنِّي لَسْتُ كَأَحَدٍ مِنْكُمْ  

[Machine] The Prophet ﷺ said, "The prayer of a person who prays sitting down is equal to half of the prayer." So, I entered upon the Prophet ﷺ while he was praying sitting down, and I said, "O Messenger of Allah, I heard that you said, 'The prayer of a person who prays sitting down is equal to half of the prayer,' and yet you are praying sitting down?" He replied, "Yes, but I am not like any one of you."  

أَنَّ النَّبِيَّ ﷺ قَالَ «صَلَاةُ الرَّجُلِ جَالِسًا نِصْفُ الصَّلَاةِ» قَالَ فَدَخَلْتُ عَلَى النَّبِيِّ ﷺ وَهُوَ يُصَلِّي جَالِسًا فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّهُ بَلَغَنِي أَنَّكَ قُلْتَ «صَلَاةُ الرَّجُلِ جَالِسًا نِصْفُ الصَّلَاةِ» وَأَنْتَ تُصَلِّي جَالِسًا؟ قَالَ «أَجَلْ وَلَكِنِّي لَسْتُ كَأَحَدٍ مِنْكُمْ»  

"I saw the Prophet ﷺ praying sitting down and I said: 'I was told that you said that the prayer of one who is sitting down is worth half of the prayer of the one who is standing up.' He said: 'Yes indeed, but I am not like any one of you.'" (Using translation from Nasāʾī 1659)  

رَأَيْتُ النَّبِيَّ ﷺ يُصَلِّي جَالِسًا فَقُلْتُ حُدِّثْتُ أَنَّكَ قُلْتَ إِنَّ صَلَاةَ الْقَاعِدِ عَلَى النِّصْفِ مِنْ صَلَاةِ الْقَائِمِ وَأَنْتَ تُصَلِّي قَاعِدًا قَالَ «أَجَلْ وَلَكِنِّي لَسْتُ كَأَحَدٍ مِنْكُمْ»  

"أتَيتُ النبِىَّ ﷺ وَهُوَ يُصَلِّى قَاعِدًا، فَقُلتُ: يَا رَسُولَ الله إِنِّى حُدثْتُ أنَّكَ قُلتَ: إِنَّ صَلاَةَ القَاعِدِ عَلَى النِّصْف مِنْ صَلاَةِ القَائِم، وَأنْتَ تُصَلِّى جَالسًا؟ فَقَالَ: أجَلْ، وَلَكنِى لَسْتُ كَأحَد مِنْكُمْ".
