[Machine] I asked the Prophet ﷺ about the prayer of a person while sitting, and he said that whoever prays standing is better, and whoever prays sitting will have half the reward of the one who prays standing, and whoever prays while lying down will have half the reward of the one who prays sitting. This is mentioned in the Hadith of Abdullah bin Warith. And in the Hadith of Ishaq, it is mentioned that he asked the Prophet ﷺ about the prayer of a person sitting and the remaining of his prayer is similar to it. And in the Hadith of Yazid, it is mentioned that the Messenger of Allah ﷺ was asked about the prayer of a person sitting, and he replied...  

سَأَلْتُ النَّبِيَّ ﷺ عَنْ صَلَاةِ الرَّجُلِ وَهُوَ قَاعِدٌ فَقَالَ مَنْ صَلَّى قَائِمًا فَهُوَ أَفْضَلُ وَمَنْ صَلَّى قَاعِدًا فَلَهُ نِصْفُ أَجْرِ الْقَائِمِ وَمَنْ صَلَّى نَائِمًا فَلَهُ نِصْفُ أَجْرِ الْقَاعِدِ لَفْظُ حَدِيثِ عَبْدِ الْوَارِثِ وَفِي حَدِيثِ إِسْحَاقَ أَنَّهُ سَأَلَ النَّبِيَّ ﷺ عَنْ صَلَاةِ الْقَاعِدِ وَالْبَاقِي مِثْلُهُ وَفِي حَدِيثِ يَزِيدَ سُئِلَ رَسُولُ اللهِ ﷺ  

[Machine] The Messenger of Allah ﷺ said: "The sitting prayer is equivalent to half of the standing prayer."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ صَلَاةُ الْقَاعِدِ عَلَى النِّصْفِ مِنْ صَلَاةِ الْقَائِمِ
