Sunan Abi Dawud, Book 3, Hadith 950 (USC-MSA) ⓘ

‘Abd Allah b. ‘Amr said : It has been narrated to me that the Messenger of Allah 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 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.

حَدَّثَنَا مُحَمَّدُ بْنُ قُدَامَةَ بْنِ أَعْيَنَ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ هِلاَلٍ، - يَعْنِي ابْنَ يِسَافٍ - عَنْ أَبِي يَحْيَى، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، قَالَ حُدِّثْتُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم 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 ‏"‏ ‏.‏
