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
