[Machine] Imran ibn Husain asked the Messenger of Allah ﷺ about praying while sitting, and he ﷺ said, "Whoever prays while standing, it is better for him. And whoever prays while sitting, he will have half the reward of the one who prays while standing. And whoever prays while lying down, he will have half the reward of the one who prays while sitting."
عَنْ عِمْرَانَ بْنِ حُصَيْنٍ سُئِلَ رَسُولُ اللهِ ﷺ عَنْ صَلَاةِ الْقَاعِدِ فَقَالَ ﷺ مَنْ صَلَّى قَائِمًا فَهُوَ أَفْضَلُ وَمَنْ صَلَّى قَاعِدًا فَلَهُ نِصْفُ أَجْرِ الْقَائِمِ وَمَنْ صَلَّى نَائِمًا فَلَهُ نِصْفُ أَجْرِ الْقَاعِدِ
